Web1 Answer. For matrixSum you just give rowsA and columnsA, as they are equal to rowsB and columnsB. For matrixProduct you need three numbers: rowsA, columnsA and columnsB. rowsB is not needed, as it is equal to columnsA. You need to change your matrixProduct function to use these three numbers at the correct places.

Consider the elementary matrix E given by. E = [1 0 0 2] Here, E is obtained from the 2 × 2 identity matrix by multiplying the second row by 2. In order to carry E back to the identity, we need to multiply the second row of E by 1 2. Hence, E − 1 is given by E − 1 = [1 0 0 1 2] We can verify that EE − 1 = I. long nails medical term
