Replace ['-L' fortranpath],... '-l...'
with local fortran compiler location and version. Likewise, replace ['-L' pardisopath], '-lpardiso' with location and name of libpardiso600-WIN-X86-64.lib file. (It helps if you rename it to pardiso.lib beforehand)
makepardiso.m should generate mexw64 files and exampleunsym.m should run successfully.
