Why would you need to return it? You're passing by reference, which modifies the original. The data's already accessible outside the function, in the original.
Arrays don't work that way, anyhow; most compilers won't let you define an array with the size of a parameter. Those which would, don't always get it right...

To return new memory, you'll need to actually allocate new memory (and need to remember to free it later).

Hi.
I have a problem with passing two dimensional array to a function.

Hello, all
For a 1-dimensional array, such as
myarr_1=1
myarr_1=2
myarr_1=3I know I can write a loop as below to show the array member one by one:
for (i in myarr_1){print i, myarr_1}Now, suppose I have a two dimensional array such as:
myarray_2=1 myarray_2=2
myarray_2=10 myarray_2=20My... (3 Replies)
I have an array of names. Each one of the name, has a number represented to it.
For example A has an ID 8, B has an ID 2.
What I am after is a for loop that when the array is in position 1, a particular variable is set to the value of position 1 in array 2
declare -a arr=("A" "B" "C"... (6 Replies)
Hi,
I have a 10*10 two dimensional array. How do I assign value to all it's 100 elements at once? I don't want to open two for loops and assign one by one.
Thanks,

SYNOPSIS
Functions/Subroutines
subroutine clacp2 (UPLO, M, N, A, LDA, B, LDB)
CLACP2 copies all or part of a real two-dimensional array to a complex array.
Function/Subroutine Documentation
subroutine clacp2 (characterUPLO, integerM, integerN, real, dimension( lda, * )A, integerLDA, complex, dimension( ldb, * )B, integerLDB)
CLACP2 copies all or part of a real two-dimensional array to a complex array.
Purpose:
CLACP2 copies all or part of a real two-dimensional matrix A to a
complex matrix B.
Parameters:
UPLO
UPLO is CHARACTER*1
Specifies the part of the matrix A to be copied to B.
= 'U': Upper triangular part
= 'L': Lower triangular part
Otherwise: All of the matrix A
M
M is INTEGER
The number of rows of the matrix A. M >= 0.
N
N is INTEGER
The number of columns of the matrix A. N >= 0.
A
A is REAL array, dimension (LDA,N)
The m by n matrix A. If UPLO = 'U', only the upper trapezium
is accessed; if UPLO = 'L', only the lower trapezium is
accessed.
LDA
LDA is INTEGER
The leading dimension of the array A. LDA >= max(1,M).
B
B is COMPLEX array, dimension (LDB,N)
On exit, B = A in the locations specified by UPLO.
LDB
LDB is INTEGER
The leading dimension of the array B. LDB >= max(1,M).
