Copy Code Copy Command Find the inverse of a 4-by-4 block matrix C=[A02,202,2B] where A and B are 2-by-2 submatrices. The notation 02,2 represents a 2-by-2 submatrix of zeros. Use symbolic matrix variables to represent the submatrices in the block matrix. Get syms A B [2 2...
In Matlab, the Inverse function is obtained by applying the ‘ finverse ’ command. This command returns the value of the given function variable. In finverse f stands for function and after finverse, there will be parameters or argument list inside the brackets depending upon the requirement. i...

Tips It is seldom necessary to form the explicit inverse of a matrix. A frequent misuse ofinvarises when solving the system of linear equationsAx=b. One way to solve the equation is withx = inv(A)*b. A better way, from the standpoint of both execution time and numerical accuracy, is...
This is how our input and output will look like in the MATLAB command window: Input: M = [3 2 3; 4 2 1; 3 4 1]; I = inv(M) I*M Output 1: (Inverse matrix) Output 2: (This should be an identity matrix) As we can see in the output 1, the function ‘inv’ has given ...
