(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem

I have a 4 x 4 matrix filled with imaginary numbers.

Each entry in the matrix is on the level of i0.XXXX.

To be more precise, it is an admittance matrix (for a power system) based on voltages and currents. I have to find the inverse in order to find the impedance matrix. I have the solution in front of me, yet with my calculator I keep getting a different answer. The answer my calculator gives is just the negative of what the solution gives.

Is there any easy mathematical way of solving matrices of this kind? I have looked online and no source seems to mention imaginary numbers; and I have yet to be taught it through 5 years of college.

Also, is there anything I can use online that can calculate it for me that I haven't found yet?

2. Relevant equations

I know all of the general methods for solving matrices. This is not a questions about solving one single matrix.

3. The attempt at a solution

See above.
