# njScaleV

Scales a matrix

### FORMAT

`

  void njScaleV(*m, *v)
  NJS_MATRIX *m
  NJS_VECTOR *v

`

### PARAMETER

  `*m` | Calculation matrix
  `*v` | Scaling ratio along the X, Y, and Z axes

### RETURN

  None

### DESCRIPTION

  Scales arbitrary matrix m. When parameter m is NULL, the current matrix is scaled.

### EXAMPLE

      The following scales the current matrix by 0.5 along the X axis,
      1 along the Y axis, and 2 along the Z axis.

      NJS_MATRIX stack[10];
      NJS_VIEW view;
      NJS_VECTOR v;
      v.x = 0.5f;
      v.y = 1.f;
      v.z = 2.f;
      njInitMatrix(stack, 10);
      njInitView(&view);
      njSetView(&view);
      njClearMatrix();
      njPushMatrix(NULL);
      njScaleV(NULL, &v);
      njPopMatrix(1);

### NOTE

  For a matrix [M] and multiplicative scaling matrix [S], [M] = [S] * [M]. Care must be taken with the order in which matrices are multiplied.
