How do you find the inverse of a matrix
WebMar 5, 2024 · To find the inverse of a matrix, we write a new extended matrix with the identity on the right. Then we completely row reduce, the resulting matrix on the right will be the inverse matrix. Example 2. 4. ( 2 − 1 1 − 1) First note that the determinant of this matrix is. − 2 + 1 = − 1. hence the inverse exists. WebNote: also check out Matrix Inverse by Row Operations and the Matrix Calculator . We can calculate the Inverse of a Matrix by: 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!

WebSep 17, 2024 · Solution. Consider the elementary matrix E given by. E = [1 0 0 2] Here, E is obtained from the 2 × 2 identity matrix by multiplying the second row by 2. In order to carry E back to the identity, we need to multiply the second row of E by 1 2. Hence, E − 1 is given by E − 1 = [1 0 0 1 2] We can verify that EE − 1 = I.
