Hi,
I need to find eigen values of a 11x11 matrix. I tried to solve it on matlab but unfortunately whenever i try to find the eigenvalues using function eig or determinant using determinant function, MATLAB just keep on saying that it is busy. The solution is on for almost 10 days and so far I have received no result. I am attaching the program with this querry. If anyone can help it would be really helpful thank you.
clear all;

Solving such a complicated matrix symbolically is not a good strategy. Especially considering that you have a single equation and several unknowns. Your system is under-determined, and there can be a potentially infinite number of solutions. Using numerical techniques are better for such problems. Can you explain the background of this problem? Maybe we can suggest some alternative solution.
