TRANSPOSE Function

Transposes the input array.

Usage

a = INDGEN(10)

; Create a 10-element row vector, a.

b = TRANSPOSE(a)

; Create a 10-element column vector, b using the TRANSPOSE function

INFO, a, b

a             INT           = Array(10)
b             INT           = Array(1, 10)

Example 2

TRANSPOSE can also be used to shift the elements of a square array around the diagonal. For example, suppose you have the following array:

Example 3

Here is what an aerial image looks like before and after applying TRANSPOSE.

Figure 2-123 TRANSPOSE has been used with this 512-by-512 aerial image to flip it diagonally (rotate it and create a mirror image).

Figure 2-124 TRANSPOSE has been used with this 512-by-512 aerial image to flip it diagonally (rotate it and create a mirror image).

Example 4

a = INDGEN( 2, 4, 3 )    &    PM, a
0       2       4       6
1       3       5       7

8      10      12      14
9      11      13      15

16      18      20      22
17      19      21      23

PM, TRANSPOSE( a, d=[0,2] )

0       2       4       6
8        10      12      14
16      18      20      22
