Here are three ways to find the inverse of a matrix:1. Shortcut for 2x2 matrices For , the inverse can be found using this formula: Example: 2. Augmented matrix method Use Gauss-Jordan elimination to transform [ A | I ] into [ I | A-1 ]. Example: The following steps result in...
A matrix that is not invertible is called asingular matrix. By the proposition above, a singular matrix is a matrix that does not have full rank. For this reason, a singular matrix is also sometimes calledrank-deficient. Uniqueness of the inverse PropositionIf the inverse of a matrix exists,...
Step 1: calculating the Matrix of Minors, Step 2: then turn that into the Matrix of Cofactors, Step 3: then the Adjugate, and Step 4: multiply that by 1/Determinant. But it is best explained by working through an example! Example: find the Inverse of A: ...
