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).
