This is the matrix for which we need to compute the inverse matrix. Step 1: Input a 4X4 matrix across the cells A1:E4 as shown in the screenshot below. See the output in an array of cells B1:C5.Įxample #2 – Compute Inverse of a 4X4 Matrix We can achieve the matrix multiplication by using the MMULT function in excel. The multiplication should result in an identity matrix. The way to check it is to multiply matrix A and A -1. We also can check whether the inverse we get through the MINVERSE function is correctly captured or not. You can see across the cells B1:C2 the matrix is inverse of the original matrix A. But in this case, you need to hit Ctrl + Shift + Enter keys so that the formula gets converted into an array formula which looks like this and works along with all the cells associated with the inverse of A. Step 4: To see the output of the formula every time we need to press the Enter key. Note that the array we are providing as an argument to the function MINVERSE consists of the cells with values for original matrix A. Step 3: Provide an array argument for the MINVERSE function as B1:C2 and close the parentheses to complete the formula. It is mandatory to select all the cells where your inverse will be computed. Double click to select the MINVERSE out of those so that you can compute the inverse of matrix A. You will see the range of formulae associated with the keyword. Step 2: In cell B4, start typing the formula for matrix inverse =MINV. These are the ranges where the inverse of matrix A will be computed. Here I have chosen cells A1:C5 as a range for the inverse of matrix A. Step 1: Decide a range of 4 cells (since we have a 2X2 matrix) in the same excel sheet, which will be holding your inverse of matrix A. Suppose we have a 2X2 square matrix, as shown in the image below.

Let’s understand how to create the Inverse Matrix in Excel with some examples. In this article, we will see how to compute the inverse of a square matrix.
The inverse matrix computed is of the size same as the original matrix.Īrray – Is an array of values representing a matrix. The inversed matrix has the size same as the original matrix. MINVERSE Function to Compute Inverse of a MatrixĮxcel MINVERSE function allows a user to compute the inverse of any square matrix which has a non-zero determinant. Mathematicians will be happy to know if any function can work for them and compute the inverse of a matrix for them. It sometimes becomes a very tedious job to compute the inverse of a matrix. If we put both these values in the formula above, we can get the inverse of any matrix A. Excel functions, formula, charts, formatting creating excel dashboard & others
