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
