The calculator computes the adjugate matrix of a given NxN matrix and uses the result to compute also the inverse matrix. The calculator shows the calculation of every element of the adjugate matrix. The input field N defines the number of rows and columns. The input field digits is for setting the number of displayed digits. With setting of N the related matrix field will be displayed for input of the matrix elements. With 'Start calc' the computation of the adjugate and inverse matrix starts.
