Solving System of Linear Equations

(OP)
Is there a simple command in Fortran for solving system of linear equations. Like matlab has x = A\B to solve Ax=B. Thanks

As IRstuff said the answer is "NO" - you have to write the source yourself.

But just about every introductory book on Fortran uses the Gaussian elemination to solve linear equations in their text as an example. Otherwise a Google search throws up sites like http://library.lanl.gov/numerical/bookfpdf.html which gives complete fortran listings of various methods to solve this rather trivial problem.

Digital Equipment Corp. had a Scientific Subroutine Package
(SSP) written in F. and I am sure it has what you need.

If you want something faster than Gaussian, look up Cholesky/Choleski LU Decomposition.
