RM

The RM procedure performs formatted input 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, simply defining an array at the IDL command line creates an array the standard image processing convention: “column” refers to the first index of the array and “row” refers to the second.

The RM procedure is used extensively in the examples in the IDL Advanced Math and Stats. For multidimensional arrays, defining an array interactively using RM is equivalent to defining the same array using normal IDL syntax and then transposing the array.
