Read the instructions. Matrix dimension: To calculate inverse matrix you need to do the following steps. Set the matrix (must be square) and append the identity matrix of the same dimension to it. Reduce the left matrix to row echelon form using elementary row operations for the whole matrix (including the right one).
Just so, Determinants and inverses matrix has an inverse exactly when its determinant is not equal to 0. Thereof, Adjoin the identity matrix onto the right of the original matrix, so that you have A on the left side and the identity matrix on the right side. It will look like this [ A | I ]. Row-reduce the matrix until the left side to the Identity matrix. When the left side is the Identity matrix, the right side will be the Inverse [ I | A-1 ]. In this manner, The identity matrix also has the property that, when it is the product of two square matrices, the matrices can be said to be the inverse of one another. In fact, The adjugate matrix and the inverse matrix This is a version of part of Section 8.5. The adjugate of a square matrix Let A be a square matrix. By de\fnition, the adjugate of A is a matrix B, often denoted by adj(A), with the property that AB = det(A)I = BA where I is the identity matrix the same size as A.

When is the pseudo inverse of the matrix equal to the matrix?
The Moore-Penrose pseudo inverse is a generalization of the matrix inverse when the matrix may not be invertible. If Ais invertible, then the Moore-Penrose pseudo inverse is equal to the matrix inverse. However, the Moore-Penrose pseudo inverse is defined even when Ais not invertible.
