3-30 Full Command and Function Reference
CNRM
Type: Command
Description: Column Norm Command: Returns the column norm (one-norm) of the array argument.
The column norm of a matrix is the maximum (over all columns) of the sum of the absolute
values of all elements in each column. For a vector, the column norm is the sum of the absolute
values of the vector elements. For complex arrays, the absolute value of a given element (x, y) is
x
2
y
2
+
.
Access: !Ø
OPERATIONS CNRM ( Ø is the left-shift of the 5key).

Type: Command
Description: Matrix to Columns Command: Transforms a matrix into a series of column vectors and returns
the vectors and a column count, or transforms a vector into its elements and returns the
elements and an element count.
→
COL introduces no rounding error.
Access: !´
MATRIX COL →COL ( ´ is the left-shift of the Pkey).

Type: Command
Description: Columns to Matrix Command: Transforms a series of column vectors and a column count into a
matrix containing those columns, or transforms a sequence of numbers and an element count
into a vector with those numbers as elements.
All vectors must have the same length. The column or element count is rounded to the nearest
integer.
