how to calculate the inverse of a matrix in matlab

To calculate the inverse of a matrix in Matlab, you can use the inv() function. Here is an example:

main.m
A = [1 2; 3 4]; % define matrix A
inv_A = inv(A); % calculate the inverse of A

3 lines

This will compute the inverse of A and store it in the variable inv_A. Note that not all matrices have inverses, so it's important to check that your matrix is invertible before using this method. You can also use the backslash operator (\) to solve systems of equations instead of computing the inverse directly.
