I got this cofactor working without errors and i get a numbers back. Is there a way you can tell your getting the correct numbers back. Cuz they dont look right ?
float MatrixCofactor(Matrix &jug, int row, int col){
	Matrix naix;
	int counterr = 0;
	int counterc = 0;
	
	for(int i = 0; i < 3; i++){
		for(int j = 0; j < 3; j++){
			if((row != i) && (col != j)){
				naix.m33[counterr][counterc] = jug.m33[j];
				counterc++;
			}
		if(row == j){
			counterr++;
			counterc = 0;}
		}}
	float leo = {(  naix.m33[0][0] * naix.m33[1][1] * naix.m33[2][2])
					+(naix.m33[0][1] * naix.m33[1][2] * naix.m33[2][0])
					+(naix.m33[0][2] * naix.m33[1][0] * naix.m33[2][1])
					
					-(naix.m33[0][0] * naix.m33[1][2] * naix.m33[2][1])
					-(naix.m33[0][1] * naix.m33[1][0] * naix.m33[2][2])
					-(naix.m33[0][2] * naix.m33[1][1] * naix.m33[2][2])};
					
	return leo;
	}
void XcoFactor(Matrix &jug){
	Matrix tmp;
	int col = 0;
int row = 0;
	CopyMatrix(jug, tmp);
	for(row = 0; row < 4; row++){
		for(col = 0; col < 4; col++){
			jug.m33[row][col] = MatrixCofactor(tmp, row, col);
		}}
}
