Print a GSL matrix.

print_matrix.c

#include <stdio.h>
#include <stddef.h>
#include <gsl/gsl_matrix.h>

int print_matrix(FILE *f, const gsl_matrix *m)
{
        int status, n = 0;

        for (size_t i = 0; i < m->size1; i++) {
                for (size_t j = 0; j < m->size2; j++) {
                        if ((status = fprintf(f, "%g ", gsl_matrix_get(m, i, j))) < 0)
                                return -1;
                        n += status;
                }

                if ((status = fprintf(f, "\n")) < 0)
                        return -1;
                n += status;
        }

        return n;
}

Hi
I would like to know the format specifiers for the complex elements of a complex matrix. Thanks!
