SPREAD — Add a dimension to an array

Description

Replicates a SOURCE array NCOPIES times along a specified dimension DIM.

Syntax

RESULT = SPREAD(SOURCE, DIM, NCOPIES)

Arguments

SOURCE Shall be a scalar or an array of any type and a rank less than seven.
DIM Shall be a scalar of type INTEGER with a value in the range from 1 to n+1, where n equals the rank of SOURCE.
NCOPIES Shall be a scalar of type INTEGER.

Return value

The result is an array of the same type as SOURCE and has rank n+1 where n equals the rank of SOURCE.

Example


PROGRAM test_spread
  INTEGER :: a = 1, b(2) = (/ 1, 2 /)
  WRITE(*,*) SPREAD(A, 1, 2) ! "1 1"
  WRITE(*,*) SPREAD(B, 1, 2) ! "1 1 2 2"
END PROGRAM
