Hi Fawad,
You can use a for-loop and the "eig" function to find the eigenvalues of the three matrices you have, by grouping the matrices into a cell array and iterating over it.
Refer to the following example:
A=[1 2;3 4],
B=[5 6;7 8];
C=[9 10;11 12];
D={A,B,C}; % Creating the cell array
for i=1:3
eig(D{i})
end
Refer to the following documentation link for more information about the "eig" function: http://www.mathworks.com/help/matlab/ref/eig.html
Best,
Farouk
