For a square matrix of order 2, finding the minors is calculating the matrix of cofactors without the coefficients. For larger matrices like 3x3, calculate the determinants of each sub-matrix. The determinant of the sub-matrix obtained by removing the first row and the first column is: ei−fh e i − f h $, do the same for all combinations of ...

A cofactor is affected from the minor of the submatrix. ... Summary. Matrix Cofactor Calculator ...

Matrix Minors Calculator This website will help you to find minors of any dimensional square matrix. A matrix is called square matrix if numbers of column is equal to numbers of rows in the matrix. Enter matrix in input field given below for entering new row enter values from next line and use space to separate values within row.

Cofactor of a matrix is related to its minor. Once the minor has been computed, we add the two numbers a and b. The number obtained as a result of adding these two numbers is made the value of the power of -1. It is denoted as: Here, is the minor and represents the cofactor.
