Hi all,

I am new to Intel Fortran Compiler. Thank you in advance for bearing my questions.

I am trying to solve a nonlinear equation system with 2 unknowns. I was planning to use the NEQNF in IMSL. But I found that it is no longer available in Intel Fortran Compiler. (I use the student version.)

I was wondering whether there is any substitute in MKL to solve the nonlinear equation system. I only found a least-square minimizer: dtrnlsp. Did I miss anything? Or does it mean that I should rewrite my problem into minimization?

Any guidance is appreciated. Thank you so much!

yes, mkl provides only nonlinear least square problem solver. There are a number of such C/F examples show how to run this code into mklroot\examples\solverf\ directory
