SciTopia: LiveCode in Science

[François Chaplais]

Sources for BLAS can be found at http://www.netlib.org/
It is in Fortran and is the successor  of LINPACK on which the early MATLAB 
http://www.mathworks.com/
http://en.wikipedia.org/wiki/MathWorks
was based.
It is most probable that BLAS has been optimized and is present in your platform OS.

My field of interest is applied mathematics, notably for engineers. The objects I consider are generally continuous and differentiable.

One has to know that in the end, most of nonlinear problems will be solved by solving a sequence of linear problems
a) if you want to solve nonlinear (but differentiable) equations, chances are that you will end up using the Newton method, which is a succession of linear problems
b) if you do optimization, many algorithms can be expressed as solving a succession of least square problems (which is a linear problem).

So, if you can solve linear problems, you can solve many other problems.

I am interested in Livecode for two reasons:
a) if you look at the price of a Matlab license, it is prohibitive
b) Livecode has the GUI and object hierarchy included from the start, with a nice language.

By contrast, building a GUI in Matlab is a PITA.

Best regards,
	François
