This post is dedicated to some important properties regarding adjoint of matrix. If, you want to go through their proves then click particular property. Note that these properties are only valid for square matrices as adjoint is only valid for square … [Continue reading]
Inverse of any Matrix is unique
In this post, I am going to discuss few properties regarding inverse of matrices and its uniqueness. If, we have any square matrix A then we cannot have more than one inverse of matrix A. In other words, we can say that inverse of any matrix is … [Continue reading]
How to find Inverse of a Matrix ?
Inverse of matrix is calculated using adjoint and determinant of matrix. The inverse of matrix A = adj (A) /|A| i.e inverse of any matrix A is equal to adjoint of A divided by determinant of A. In the last posts, I discussed about calculating … [Continue reading]
How to find Adjoint of Matrix ?
In the last posts, I discussed about finding co-factors of all the elements present in the matrix. To find adjoint of a given matrix, we simply replace all the elements present in the matrix by their co-factors and then we take transpose of the … [Continue reading]
How to calculate determinant of matrix using Co-factors?
In the last post, I discussed about calculating minor of each element present in the matrix. Also, In the last posts, I discussed about calculating determinants of matrices. You will notice here that the method I used there was related to co-factors. … [Continue reading]
