The inverse of a matrix is the matrix that when multiplied with itself, gives an identity matrix.
You can take a look at the example above, the second matrix is the inverse matrix of A. Multiplication with A gives the same dimension identity matrix.
How To Calculate Inverse Of A Matrix In MatLab®?
>> A = [3 6 3; 6 -5 3; 6 -4 6];
inv(A)
ans =
0.1250 0.3333 -0.2292
0.1250 -0.0000 -0.0625
-0.0417 -0.3333 0.3542
>> It is very basic to calculate the inverse of a matrix in Matlab®. You just need to use the ‘inv()’ command in the command window. As you see in the example above in the MatLab® command window, we created a 3×3 matrix ‘A’ then wrote ‘inv(A)’ then hit the Enter key.
You can see the answer above.
