Math library for Free Basic

[v3cz0r]

Fixed, patch is on CVS (http://cvs.sourceforge.net/viewcvs.py/fb...ortby=date), thanks.

I may never get PRINT USING to work fully, that is one of the most hacked statements ever, loads of odds that only appear when compiling old sources.

Thanks!

BTW, the following code compiles in QB but not in FB:

Code:

DIM I AS INTEGER, X AS DOUBLE

I = 5
X = 1.23

PRINT I; USING "#####.##"; X

In FB you must write:

Code:

PRINT I;
PRINT USING "#####.##"; X

Not a real problem, but a slight loss in compatibility

What if you put in a colon, like so?

PRINT I; : PRINT USING "#####.##"; X

PRINT I; : PRINT USING "#####.##"; X

This works, but QB allows a single PRINT

The math library has been updated:

* Added 3 more algorithms for nonlinear optimization (Marquardt, BFGS, Simplex)

* Split source code into more modules for smaller executables

* Added a batch file to recompile the library

* Updated the PDF documentation

The nonlinear equations solvers, which I have promised some time ago, will be added soon. I wanted to implement the optimization algorithms first because most equation solvers are derived from them.

is this a physic library ? cause i can really use one 8)

I already use these algorithms in chemical applications, so I think they can be used in physics too 8)

What is your problem exactly ?

[jdebord]

The library has been updated :

* Added 3 algorithms for nonlinear equations in one unknown (Bisection, Secant, Newton-Raphson)

* Added 2 algorithms for systems of nonlinear equations in several unknowns (Newton-Raphson, Broyden)

Best regards

* BastetFurry smells the possibility for a free (as in mind and beer) competitor for programms like MathLab or Derive ^.^

what I mean is Physic for game, something like calculation for velocity, accel, momentum, rigid body dynamics, stuff like that....
