determinant?! HELP!!!

hey guys, i am having trouble writing a program to compute the determinant of a matrix. i need to write a function that'll find the determinant of matrix if reading from a file. the file has 6 matrices, each one no more than a 10x10 matrix. for each set of data, m, n, and its matrix is followed. for example, the file might contain:

5 5

1.0 3.4 5.3 5.4 1.8
2.3 0.1 9.6 3.6 2.6
3.4 5.3 1.3 4.2 1.1
1.2 1.3 4.3 4.4 5.4
8.8 7.9 8.3 5.9 6.2

so this means its a 2x2 matrix: [1.0, 3.4, 5.3, 5.4, 1.8; 2.3, 0.1, 9.6, 3.6, 2.6; 3.4, 5.3, 1.3, 4.2, 1.1; 1.2, 1.3, 4.3, 4.4, 5.4; 8.8, 7.9 8.3, 5.9, 6.2] with m=5, and n=5.

how would i get my program to understand that the first line is only the dimension of the matrix, and the lines below it are the matrix? im thinking of using a recursive function...
thanks!!!

Put some thought into it. It's not hard.

Code:

---

while not all done
    read size into y and x
    for yc = 0; yc < y; yc++
        for xc = 0; xc < x; xc++
            read into matrix[yc][xc]

---

Wheeeeee.

Quzah.
