## This is Makefile for SDPA-C

## Requirement    :: wget, git 
## Recommendation :: gcc (>= 4.2), g++ (>=4.2), gfortran (>= 4.2),

## Before the compilation, examine the file 'make.inc'

## To compile SDPA-C, 'make all'
##  This will compile SuiteSparse, MUMPS, OpenBLAS, then SDPA-C
## To compile mex, 'make matlab' or 'make octave'
