Good morning,

 

I am currently working on a linear programming project using GLPK and
Java. 

 

I have built the matrix that I need to give to GLPK (with the three
arguments ia, ja and ar with the glp_load_matrix method) and I have set
all the coefficients for each constraint of my problem. 

 

I would like to print all the coefficients from the ar array to have an
overview of the matrix from GLPK (before the solving) but I don’t know
which function I should use for that. I tried to use
GLPK.glp_get_row_prim for each line and each column of that same line
(with a loop) but the values are all set at 0 and it seems fair as this
function is used for LP relaxation…

Thank you for your help.

 

Regards,

 

Titouan
