3-40 Full Command and Function Reference
COL+
Type: Command
Description: Insert Column Command: Inserts an array (vector or matrix) into a matrix (or one or more
elements into a vector) at the position indicated by n
index
, and returns the modified array.
The inserted array must have the same number of rows as the target array. n
index
is rounded to the
nearest integer. The original array is redimensioned to include the new columns or elements, and
the elements at and to the right of the insertion point are shifted to the right.
Access: !´
MATRIX COL COL
+ ( ´ is the left-shift of the Pkey).
!Ø
CREATE COLUMN COL
+ ( Ø is the left-shift of the 5key).

Example 3:
COLCT('X^Z*Y*X^T*Y')
returns

COLLECT
Type: Command
Description: Factorizes a polynomial or an integer. This command is almost identical to the COLCT command
and similar to the FACTOR command. Unlike FACTOR it does not factorize symbolically into
square roots. It is included to ensure backward-compatibility with earlier calculators.
Access: Algebra, …×
Input: An expression or an integer
Output: The factorized expression, or the integer expressed as the product of prime numbers.
Flags: Exact mode must be set (flag –105 clear).
Numeric mode must not be set (flag –3 clear).
Radians mode must be set (flag –17 set).
If complex inputs are given, complex mode must be set (flag –103 set).
