I have to solve problem find root n variable m equation ?

Newton -raphson method of Open Cascade math utility support only n variables * n equation.

But I have to solve problem find n variables * m eqation. So i have to least - square method for redundant eqation solve ..

math_Jacobian classes is only supported square matrix. But I have to use Jacobian matrix not square.

so..newton -raphson method have to support n*m Please help me..

Please send me know how to solve this problem and send me sample source.

Thanks in advanced

Best regard

Hi,

the class math_FunctionSetRoot calculates the root of a set of N functions of M variables.

The another way is to solve corresponding minimisation problem by any suitable method of minimization from math (in fact math_FunctionSetRoot uses minimization algorithm to find roots, but you can form more appropriate for your problem function).

Best regards,

Igor
