Question

how to read a matrix from a file in C language?

Answer 1

Depends on the structure of the file. Assuming the matrix is written out into the file like human beings write it, then if you know the number of columns per row, then all you need to do is do something like this..

for (i = 0; i < no_rows; i++)

for (j = 0; j < no_columns; j++)

scanf ("%d", &a[i][j]);
