# Gor; Grad; Gramschmidt; Greduce - HP 48gII Advanced User's Reference Manual

Graphing calculator.

## GOR

Type:
Command
Description: Graphics OR Command: Superimposes grob
pixel of grob
GOR uses a logical OR to determine the state (on or off) of each pixel in the overlapping
portion of the argument graphics object.
If the first argument (stack level 3) is any graphics object other than PICT, then grob
returned to the stack. If the first argument (level 3) is PICT, no result is returned to the stack.
Any portion of grob

GRAD clears flag –17 and sets flag –18, and displays the GRD annunciator.
In Grads angle mode, real-number arguments that represent angles are interpreted as grads, and
real-number results that represent angles are expressed in grads.

### GRAMSCHMIDT

CAS:
Find an orthonormal base of a vector space with respect to a given scalar product.

### GREDUCE

CAS:
Reduce a polynomial with respect to a Grœbner basis.

### GRIDMAP

Type:
Command
Description: GRIDMAP Plot Type Command: Sets the plot type to GRIDMAP.
When plot type is set GRIDMAP, the DRAW command plots a mapping grid representation of
a 2-vector-valued function of two variables. GRIDMAP requires values in the reserved variables
EQ, VPAR, and PPAR.
VPAR has the following form:
For plot type GRIDMAP, the elements of VPAR are used as follows:
• x

• y
and y
