General::matrix

Details

  • This message is generated when the indicated expression is expected to be a matrix.
  • For the purpose of this message an expression is a matrix if the expression is a list with at least one element, all of the elements are lists of the same length, and none of the elements of the inner lists are lists.
  • This message can be generated by most linear algebra functions and by graphics functions, such as PseudoInverse, that use matrix arguments.
  • Off[message] switches off the message; On[message] switches it on. For example: Off[General::matrix].

Examples

Basic Examples  (1)

The argument of PseudoInverse is expected to be a matrix:

Wolfram Language code: PseudoInverse[{{1.3, 2.5}, {3.1, {2.7}}}]

This shows a correct use of PseudoInverse:

Wolfram Language code: PseudoInverse[{{1.3, 2.5}, {3.1, 2.7}}]
