what is the corresponding subroutine of ZXMIN/LINV1F in fortran 90

[feelinginwind]

hey,

I am new to fortran, totally new here and hope I can get some help. any suggestion are appreciated.

I need to use two subroutines--ZXMIN/LINV1F, but the fist one is not in the IMSL for a long time. so, my question is: what is the corresponding subroutine of ZXMIN/LINV1F in fortran 90? or, how I can use them if there is not a corresponding one after fortran 77.

thanks for answering in advance

Hi,

LINV1F is not an intrinsic Fotran routine, neither in F77 nor in F90, so you will always need a library to use it.

Google immediately turns up

http://ib.cnea.gov.ar/~fiscom/Libreria/imsl_old/linv1f.f,

the source code for LINV1F. Looking at this file, it seems like it shouldn't be too hard to port to F90.

Additionally, since all LINV1F does is matrix inversion, you can probably find a suitable replacement for it in any BLAS package, which exist in abundance for Fortran 90 as well.

Hope that helps,
Matt
