And this strange, because in most texts the adjoint of a matrix and the cofactor of that matrix are tranposed to each other. But in MATLAB are equal. I found a bit strange the MATLAB definition of the adjoint of a matrix.1 Answer. Sorted by: 1. To minimize calculations, you want to expand the determinant along a row/column that has as many zeros as possible. For example, expanding along the first column, we have. det⎛⎝⎜⎜⎜2 0 0 0 7 −5 0 0 −1 8 3 0 4 11 −13 1 ⎞⎠⎟⎟⎟ = 2 ⋅ det⎛⎝⎜−5 0 0 8 3 0 11 −13 1 ⎞⎠⎟ − 0 ⋅ det ...In such a case, we say that the inverse of A is B and we write A -1 = B. The inverse of A is given by. The necessary and sufficient condition for the existence of the inverse of a square matrix A is that |A| ≠ 0. Properties of inverse matrix: If A and B are invertible matrices of the same order, then.

First, we have to calculate the minors of all the elements of the matrix. This is done by deleting the row and column to which the elements belong and then finding the determinant by considering the remaining elements. Then, find the cofactor of the elements. It is done by multiplying the minor of the element with -1 i+j.
