WebFind the adjugate; Inverse matrix of the matrix A is the scalar multiplication of the adjugate by 1 det ( A). For example, let us find the inverse matrix of the matrix A = (10 20 10 4 5 6 2 3 5) Firstly, using the 3x3 matrix determinant formula, we obtain det(A) = − 70.

Here's a method for inverting matrices using row reduction, which I think is what you are after: Let A be an n × n matrix. Let B be the n × 2 n matrix obtained by placing the n × n identity matrix to the right of A : B = ( A I n). Now, perform row reduction on this matrix until the left half is the identity matrix (or has a row of zeros). gressoney wetter
