Matrix Functions
COLNORM
Column Norm. Finds the maximum value (over all columns) of
the sums of the absolute values of all elements in a column.
COLNORM (mahrx)
COND
Condition Number. Finds the 1-norm (column norm) of a square
matrix.
COND {matrix)
CROSS

Determinant of a square
matrix.
DET {matrix)
DOT
