MINVERSE
Returns the inverse of a matrix.
Syntax:
MINVERSE(array)
- returns the inverse of the square matrix array, which may be either an inline array or a range, containing all numbers.
- MINVERSE returns an array, and must be entered as an array formula (for example by using Cntrl-Shift-Enter rather than just Enter).
- A matrix has an inverse if and only if its determinant is not zero.
Example:
=MINVERSE({4;2|3;2})
- when entered as an array formula in cell B3, returns {1;-1|-1.5;2}, so that cells B3, C3, B4, C4 show 1, -1, -1.5, 2 respectively.
=MINVERSE(A1:B2)
- when entered as an array formula in cell B3, where cells A1, B1, A2, B2 contain 4, 2, 3, 2 respectively, returns 1, -1, -1.5, 2 in cells B3, C3, B4, C4 respectively.
