ForMatmul: A Fortran library that overloads the matmul function to enable efficient matrix multiplication with/without coarray.

use formatmul

c = matmul(a,b, option='m1', transA=.true., transB=.true., coarray=.true.)

If you want to use ForMatmul as a dependency in your own fpm project, you can easily include it by adding the following line to your fpm.toml file:

[dependencies]
formatmul = {git="https://github.com/gha3mi/formatmul.git"}
