The CLAPACK library was built using a Fortran to C conversion utility

called f2c. The entire Fortran 77 LAPACK library is run through f2c to
|
|
obtain C code, and then modified to improve readability. CLAPACK's goal

is to provide LAPACK for someone who does not have access to a Fortran

compiler."""
