Java Matrix Transpose strangeness going on
- by user1459976
ok so im making my own Matrix class. and i have a transpose method that transposes a matrix. this is the block in the main method
Matrix m1 = new Matrix(4,2);
m1.fillMatrix(1,2,3,4,5,6,7,8);
System.out.println("before " + m1.toString());
m1.transpose();
System.out.println("after " + m1.toString());
this is where it gets messed up, at m1.transpose(); in the transpose() method
public Matrix transpose() {
if(isMatrix2) {
Matrix tempMatrix = new Matrix(row, col); // matrix2 contents are emptied once this line is executed
for(int i=0; i < row; i++) {
for(int j=0; j < col; j++)
tempMatrix.matrix2[i][j] = matrix2[i][j];
}
so for some reason, the tempMatrix.matrix2 has the same id as this.matrix2. so when the codes executes
Matrix tempMatrix = new Matrix(row,col);
then the contents of this.matrix2 is emptied. anyone know what might be going on here?
