PM

Syntax | Arguments | Keywords | Example | Version History

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 IDL Advanced Math and Stats. For multidimensional arrays, the syntax

PM, array 

is equivalent to

PRINT, TRANSPOSE(array) 

Syntax

PM, Array₀ [, ... , Array₁₉]

Arguments

Array_n

The arrays to be displayed. The PM routine can display up to 20 arrays.

Keywords

None.

Example

; 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
