WebNov 17, 2024 · Mathematica uses capital letters for built-in functions, so try Inverse [M] instead of inverse [M] in your first code block. Or better: Simplify [Inverse [M]], since your assumptions will not do anything if you don't use Simplify or some related function. However, I don't expect the inverse to reduce to something small and readable in this case. WebDec 11, 2013 · A unique inverse matrix can only be found, if A is a square matrix, so if n = m. If that is not the case you might be able find a pseudo inverse that fulfills A − 1 A = I (the left inverse) or A A − 1 = I (the right inverse) depending on n and m. ccohs confined spaces https://vapenotik.com

WebJan 21, 2009 · The Moore-Penrose pseudo inverse is a generalization of the matrix inverse when the matrix may not be invertible. If A is invertible, then the Moore-Penrose pseudo inverse is equal to the matrix inverse. However, the Moore-Penrose pseudo inverse is defined even when A is not invertible.
