i need fastest method print it.

a simple solution m x n matrix defined double pointer type is:

/* print (m x n) matrix */ void mtrx_prn (size_t m, size_t n, float **matrix) { register size_t i, j; (i = 0; < m; i++) { char *pad = "[ "; (j = 0; j < n; j++) { printf ("%s%6.3f", pad, matrix [i][j]); pad = ", "; } printf ("%s", " ]\n"); } }

output

$ ./bin/mtrx_dyn_example [ 1.900, 2.800, 3.700, 4.600 ] [ 2.800, 3.700, 4.600, 5.500 ] [ 3.700, 4.600, 5.500, 6.400 ]

just adjust info type (e.g. int, double, etc...) needed.
