Web21 aug. 2024 · Now we will use a singular matrix and apply both the functions to find its inverse. Matlab Output: So, we can’t use inv () in case if Matrix is singular. But using the same Matrix, the inverse can be calculated using the pinv () function. Both pinv () and inv () are used to find the inverse of matrices in MATLAB. WebIf A is a matrix, then flip (A) reverses the elements in each column. If A is an N-D array, then flip (A) operates on the first dimension of A in which the size value is not 1. example B = …
