performFunction method

Matrix performFunction(dynamic function(double))

Perform a function on the matrix

• function The function to perform
• Returns The new matrix
• Example

Matrix matrix = Matrix(2, 2);
Matrix newMatrix = matrix.performFunction((a) => a * 2);

• Note The function should take a double as input and return a double

Implementation

Matrix performFunction(Function(double) function) {
  Matrix newMatrix = Matrix(_row, _col);
  for (int i = 0; i < _row; i++) {
    for (int j = 0; j < _col; j++) {
      double result = function(getAt(i, j));
      newMatrix.setAt(i, j, value: result);
    }
  }
  return newMatrix;
}
