# linear algebra: find the analytical form of the eigenvalue of a special dispersed matrix

Leave $$hat { bf H}$$ be a $$p hat {N} times p hat {N}$$ scattered matrix consisting of $$p times p$$ blocks, where each block is in size $$hat {N} times hat {N}$$. The values ​​in $$hat { bf H}$$ is illustrated below (empty places are zero):

Ask for help in finding the analytical form of eigenvalues ​​(especially the largest eigenvalue) of this matrix.
