See Additional Examples for more information on using TRANSPOSE.
Print a simple array and its transpose by entering:
; Create an array:
A = INDGEN(3,3)
TRANSA = TRANSPOSE(A)
; Print the array and its transpose:
PRINT, 'Transpose of A:'
0 1 2
3 4 5
6 7 8
Transpose of A:
0 3 6
1 4 7
2 5 8
Result = TRANSPOSE( Array [, P] )
Returns the reflection of the array along a diagonal.
The array to be transposed.
A vector specifying how the dimensions of Array will be permuted. The elements of P correspond to the dimensions of Array; the ith dimension of the output array is dimension P[i] of the input array. Each element of the vector P must be unique. Dimensions start at zero and can not be repeated.
If P is not present, the order of the dimensions of Array is reversed.
This example demonstrates multi-dimensional transposition:
; Create the array:
A = INDGEN(2, 3, 4)
; Take the transpose, reversing the order of the indices:
B = TRANSPOSE(A)
; Re-order the dimensions of A, so that the second dimension
; becomes the first, the third becomes the second, and the first
; becomes the third:
C = TRANSPOSE(A, [1, 2, 0])
; View the sizes of the three arrays:
HELP, A, B, C
A INT = Array[2, 3, 4]
B INT = Array[4, 3, 2]
C INT = Array[3, 4, 2]
