Takes a matrix descriptor

and the row in
Compare M.REG.
(1) Takes a descriptor
Transforms (X) into its LU decomposition in-situ.
The value in X is replaced by a descriptor that
defines the pivots that were required to calculate
the decomposition. The most significant digit is the
pivot for the first diagonal entry, the next most
significant for the second and so forth.
(3) Takes a matrix
and a column number

(2) Works in analogy to AND. See there.

(1) Takes a matrix
number of columns of (X).
(2) Returns the nearest machine-representable
number to x in the direction toward y in the mode

set . For x < y (or x > y ), this is the machine
successor (or predecessor) of x ; for x = y it is y.
(2) Returns x + 1 for x < y , y for x = y , or x – 1
for x > y .
(1) Returns the next prime number greater than x.
(0) 'Empty' step FWIW.
