Returns the number of row or columns, respectively, in M.
NROW({1, 0; -2, -3; 3, 3}) ⇒ 3
NROW(1:5) ⇒ 1
NCOL({1, 0; -2, -3; 3, 3}) ⇒ 2
NCOL(1:5) ⇒ 5
Returns a column vector containing a copy of M’s main diagonal.
The vector’s length is the lesser of NCOL(M)
and
NROW(M)
.
DIAG({1, 0; -2, -3; 3, 3}) ⇒ {1; -3}
