MUNIT
Returns a unit (identity) matrix of a given size.
Syntax:
MUNIT(size)
- returns the unit matrix, also known as the identity matrix I, of size size (an integer greater than zero).
- The identity matrix has ones on the leading diagonal, and zeroes elsewhere.
- MUNIT returns an array, and must be entered as an array formula (for example by using Cntrl-Shift-Enter rather than just Enter).
Example:
=MUNIT(2)
- when entered as an array formula in cell B3, returns {1;0|0;1}, so that B3, C3, B4, C4 show 1, 0, 0, 1 respectively.
