Matrix Entry and Display

PM: 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.

RM: 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.
