PM

PM

The PM procedure performs formatted output of arrays using the standard linear algebraic convention: “row” refers to the first index of the array and “column” refers to the second. By contrast, other IDL routines (such as PRINT) perform formatted output of arrays using the standard image processing convention: “column” refers to the first index of the array and “row” refers to the second.

The PM procedure is used extensively in the examples in the IMSL routines. For multidimensional arrays, the syntax:

PM, array

is equivalent to:

PRINT, TRANSPOSE(array)

This routine requires an IDL Advanced Math and Stats license. For more information, contact your sales or technical support representative.

Examples


Example 1

; Define an array arr
arr = [[1.0, 3.0], [0.0, 4.0], [2.0, 1.0]]
; Print using PM and PRINT
PM, arr & PRINT & PRINT, arr

IDL prints:

1.00000 0.000000 2.00000
3.00000 4.00000 1.00000
1.00000 3.00000
0.000000 4.00000
2.00000 1.00000
