Hi All,
I want to read MPS format file using this file.
I am able to read cofficient of objective function,number of columns, number
of rows etc.
But not able to read constraint matrix & its rhs values.
Could anyone please help in this?
is there any good documentation available other than glpk.pdf &
glpk_intro.pdf?
My program is as follows--
p<-lpx_read_mps("c:/ex2.mps")
numrows<-lpx_get_num_rows(lp)
numcols<-lpx_get_num_cols(lp)
numnz<-lpx_get_num_nz(lp)
print("objective function coefficient")
for (j in 1:numcols) {
print(lpx_get_obj_coef(lp, j))
}
print("rows names")
for (i in 1:numrows) {
print(lpx_get_row_name(lp, i))
print(lpx_get_row_prim(lp, i)) # for this it is returning me zeros only
}
print("columns Names")
for (j in 1:numcols) {
print(lpx_get_col_name(lp, j))
print(lpx_get_col_prim(lp, j))
}
Could anyone help me out?
Thanks in advance,
Ujjwal
