Java inverse matrix calculation

Question

I\'m trying to calculate the inverse matrix in Java.

I\'m following the adjoint method (first calculation of the adjoint matrix, then transpose this matrix and fina

Answer 1

Do you have to have an exact solution? An approximate solver (Gauss-Seidel is very performant and easy to implement) will likely work for you, and will converge very quickly. 19x19 is quite a small matrix. I think the Gauss-Seidel code that I used could solve a 128x128 matrix in the blink of an eye (but don't quote me on that, it's been a while).
