matrices or of one
matrix and a scalar.
Stores in result matrix
(page 152-155).
÷ For two matrices,
multiplies inverse of
matrix in X by matrix
in Y. For only one
matrix, if matrix in Y,
divides all elements of
matrix by scalar in X; if
matrix in X, multiplies
each element of inverse
of matrix by the scalar
in Y. Stores in result
matrix (pages 152-
155).

~ T 0 T 5
T 6 Conditional
tests for matrix
descriptors in the X- or
X- and Y-registers.
~ and T 0 (x ≠
0) test the quantity in
the X-register for zero.
Matrix descriptors are
considered nonzero.
T 5 (x = y) and
T
6 (x ≠ y) test if the
descriptors in X and Y
are the same. The result
affects program
execution: skip (one
line) if false (page
174).
