If you're scientific or mathematical work involves highly complex linear and non linear problem solving, then you may find that Octave provides the power you've been looking for.

Octave is a high-level language developed by the open source community which functions simply by providing a command line interface for solving linear and nonlinear numeric problems. For those that are familiar with Matlab, they will have few problems picking up Octave because it works in conjunction with the former language.

The program basically features several very powerful tools for solving the kind of linear algebra equations that would send shivers down the spine of even the most experienced mathematician. According to the developers, it also includes functions for manipulating polynomials and integrating differential and differential-algebraic equations if you know what those are in the first place! The one bonus for those familiar with other languages is that Octave can also be extended or used in conjunction with modules written in C++, C, Fortran and others.

This is an extremely complex language that only those familiar with Matlab or Fortran will pick up quickly. Anyone else should be prepared to put a lot of hours in although the problem solving skills it will provide you with seem virtually limitless.

Fractals have always been fascinating for their characteristic of never ending and rebuilding themselves each time you zoom in on them. It’s a never ending journey and a never ending world. With Fraqtive you can play with fractals, creating and editing their parameters, changing tones and shades.

If you are a mathematician you will probably understand what all the parameters stand for and what you can obtain by changing the X and Y values, the zoom factor and the rotation angle. If you are just curious like me, change the settings and see what happens. I managed to create a perfect pink rectangle which doesn’t really look like a fascinating fractal!

There is also a 3D rendering feature which is very nice, you can rotate it with the mouse and zoom in and out. Unfortunately, unlike the 2D rendering where you can zoom in infinitely times, in the 3D mode, you only have a section of your fractal to play with, but it doesn’t recalculate itself if you try to enlarge the image.

Fraqtive allows you to create your personalized fractals. The full screen mode lets you immerse fully in this psychedelic world and take screenshots for your mathematical studies or, more commonly, for beautiful wallpapers.

If you're a biomedical student or serious scientists then you'll have to perform some pretty complex linear and non linear calculations.

R is an attempt to provide a wide variety of statistical analysing - namely linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering methods and graphical techniques. The developers have chosen the S language as what they call the "vehicle of choice" for research in statistical methodology. The main strength of the program is that it can produce high quality, well defined plots including mathematical symbols and formulae. The aim has been to put control in the hands of the user although it has to be said, the user needs to know exactly what they are doing with such complex tools to get any real benefit out of it other than drawing pretty graphs. Since it's open source however, it's very open to customisation by it's users so if there's something you don't like, you can access the source code easily.

A very professional analytical tool that's strictly for experienced or Phd level scientists - beginners stay well away.

Graph is an open source application used to draw mathematical graphs in a coordinate system. Anyone who wants to draw graphs of functions will find this program useful. The program makes it very easy to visualize a function and paste it into another program. It is also possible to do some mathematical calculations on the functions.

Draw functions

Graph can draw normal functions, parameter functions, and polar functions. You can use a lot of built-in functions, e.g. sin, cos, log, etc. You may specify color, width and line style of the graphs, and the graphs may me limited to an interval. It is also possible to show a circle at the ends indicating open or closed interval.

Interact with other programs

You can save the coordinate system with graphs as an image on disk either as a bitmap (bmp), Potable Network Graphics (png) or metafile (emf). You may also copy the coordinate system into another program, e.g. Microsoft Word, either as a normal image or as an OLE object, which may be edited later by double clicking on it.

A lot of options

While still easy to use Graph has a lot of customization possibilities, e.g. fonts, colors, axes style, grids, etc. The axes, which may by normal or logarithmic, can be placed either by entering specific values, or by moving or zooming with the mouse.

Evaluate

Given an x-coordinate Graph will calculate the function value and the first two derivatives for any given function. Alternatively the function may be traced with the mouse. Graph can also fill a table with evaluated function coordinates in a user specified range. Data from the table can easily be copied into another program, e.g. Excel.

Calculate

Graph can help you calculate the area under a function in a given interval and the distance along the curve between two points on the function. The program can also show the first derivative of a function, and create tangents and normal lines to a function at given coordinates.

Point series and trendlines

You can create series of points with different markers, colors and size. Data for a point series can be imported from other programs, e.g. Microsoft Excel. It is possible to create a line of best fit from the data in a point series, either from one of the built-in models or from a user specified model.

Shadings and labels

Graph can insert shadings used to mark an area related to a function. Shadings may be created with different styles and colors in a user specified interval. In addition to the optional legend used to describe each function, a label may be added anywhere in the system. A label can contain text with different fonts, images and objects created in other programs.

Nowadays, most people use PowerPoint to create presentations and graphs for statistical data.

However, sometimes PowerPoint is not enough to give you the full control over statistical data that you need, especially if you need to create complex charts. In addition, it's expensive, as it comes as part of Office but this package is totally free.

The main purpose of TeeChart-Office is to allow you to easily create both basic and complex charts while linking them to the original data. In a few clicks, you can modify and change the chart appearance (for instance from pie chart to bar chart), export charts to their native format, insert image files, print them, share them with others and lots more.

The program offers 17 main chart types with a huge number of customisations options. You can just about anything from labeling your charts to inserting complex mathematical formulas. Some of the more advanced plotting features are only available if you upgrade to the Pro version although you won't need these unless you are designing scientific graphs. You can also easily export graphs and images to another format using a simple wizard.

The look of TeeChart-Office is not exactly great - it looks rather blocky and basic compared to PowerPoint but it's incredibly powerful, customizable and best of all, free.
