M.COPY
 
DECM
Takes a matrix descriptor in Y and a register
number in X. Copies the matrix into registers
starting at X. Returns a properly formed matrix
descriptor in X.
M.DY

\
Sets the format for date display.
M.IJ
 
DECM
Takes a matrix descriptor in X and a register
number in Y. Returns the column that register
represents in Y and the row in X. The descriptor
is saved in L. M.IJ is similar to PPC M4.
M.LU
 
DECM
Takes descriptor of a square matrix in X. Trans-
forms the matrix into its LU decomposition. The
matrix is modified in-situ. The value in X is re-
placed by a pivot descriptor that defines the pi-
vots that were required to calculate the decom-
position. The most significant digit is the pivot for
the first diagonal entry, the next most the second
and so forth.
M.REG
 
DECM
Takes a matrix descriptor in X, a row number in
Y, and a column number in Z. The descriptor is
saved in L. M.REG returns the register number
in X (popping the stack twice). It is similar to
PPC M5.
M.SQR?
 
DECM
Takes a matrix descriptor in X and tests it. Re-

DECM
Takes a matrix descriptor in X, saves it in L, and
returns the number of columns in this matrix.
