A partial pivot method is used for the LU factorisation. After that, you have to go through numerous lengthy steps, which are more time consuming in order to find the inverse of a matrix. Since the exponential function can be defined for any complex argument, we can also extend the definitions of the hyperbolic functions to complex arguments. For a 3×3 matrix, we may use the much larger and more complex formula that is also shown below. Complex Number Calculator. The Inverse matrix is also called as a invertible or nonsingular matrix.
