Hello,
I have a data array in 3-dimensions i.e., X -> BYTE = [3,360,2167]. I want to transform the data array retaining the same dimensions as X' -> BYTE = [3,2167,360]. Is there a simple function in IDL which can automatically rearrange the data to the new dimensions?
Any suggestions would be of great help.
Thanking you in advance,
Regards,
Madhavan

Would this do:
IDL> a = bytarr(3,50,100)
IDL> help, transpose(a,[0,2,1])
<Expression> BYTE = Array[3, 100, 50]
Cheers,
Helder

Here is a better example:
IDL> file1 = FILEPATH('Night.jpg', SUBDIRECTORY=['examples','data'])
IDL> read_jpeg, file1, a
IDL> help, a
A BYTE = Array[3, 1024, 512]
IDL> image(transpose(a,[0,2,1]))
This way the image is...weel, transposed.
Cheers,
Helder
