      NJS_MATRIX *m

### PARAMETERS

NJS_MATRIX *m
  calculation matrix

### RETURN VALUE

  None

### FUNCTION

- Determines the matrix expression of arbitrary matrix m.
- When parameter m is NULL, the expression is determined from the current matrix.

  Determines the matrix expression of the current matrix.

      NJS_MATRIX stack[10];
      NJS_VIEW view;
      Float det;

      njInitMatrix(stack, 10);
      njInitView(&view);
      njSetView(&view);
      njClearMatrix();
      njPushMatrix(NULL);
      det = njDetMatrix(NULL);
      njPopMatrix(1);
