## gSPPopMatrix [macro]

Pops from a matrix stack.

Syntax

    #include <ultra64.h>  /* gbi.h */
    gSPPopMatrix(Gfx *gdl, u32 param)
    gsSPPopMatrix( u32 param)

Arguments

- gdl is the pointer to the graphics display list.

- param is the The flag field identifying the matrix stack to pop:
  G_MTX_MODELVIEW (The modelview matrix stack)
  G_MTX_PROJECTION (The projection matrix stack)(not implemented)

Explanation
Pops from one matrix stack. The modelview matrix stack is 10 levels deep, and the projection matrix stack is 1 level deep (so it is impossible to pop a projection matrix stack). For details, see Section 11.3, "Matrix State," in the N64 Online Programming Manual.

Notes
If the stack is empty, the command is ignored.
