Off-lately, i have been working on some code which requires conversion of MATLAB's "fsolve" function into C/C++. Although, i am pretty aware that MATLAB's fsolve is speed efficient and requires no more tuning to get to the kernel level language. But, there is some application i am working on which requires the fsolve calculations to be done at kernel level and hence C/C++ or any UNIX/LINUX base shell script would do.
Please let me know if i am unclear or do write in case of any doubts or if some solution already exists and i am unaware. (coz, i already searched a lot on the internet and i wasn't able to.
