Thread: need help solving Gaussian method for inverse

i got some code but its not working or compiling. i need to use this code to find inverse of any size matrix. specific help would be appreciated. here is my code:

public static double[][] GaussianEliminverse(double[][] A,int B)
{
double[][] b = new double[B][B];
for (int row = 0; row < B; row++) {
for (int col = 0; col < B; col++) {
if (row == col) {
b[row][col] = 1;
} else {
b[row][col] = 0;
}
}
}

double pivot, factor;
int i;
int j;
int k;

int n = b.length;

for (i = 0; i < n; i++) {
pivot = A[i][i];

for (j = 0; j < n; j++)
A[i][j] = A[i][j] / pivot;

b[i][j] = b[i][j] / pivot;

for (k = 0; k < n; k++) {
if (k != i) {
factor = A[k][i];

for (j = 0; j < n; j++)
A[k][j] = A[k][j] - factor * A[i][j];

b[k][j] = b[k][j] - factor * b[i][j];
}
}
}
for (int row = 0; row < b.length; row++) {
for (int col = 0; col < b[row].length; col++) {
System.out.print(b[row][col] + " ");
}
System.out.println();
}
return (b);
}
