A block structured matrix is built by putting together submatrices, where each submatrix is a block. An example is a Hanowa matrix. If m is an integer and d is a real number, then a
 Hanowa matrix has block structure
 We will discuss block matrices in Section 9.1.4.

 Using the MATLAB functions eye and diag, construct a
 Hanowa matrix
 with

 Find the eigenvalues of

 Using
 build Hanowa matrices of dimensions
 and
 and compute their eigenvalues.

 From your results in parts
 and
 propose a formula for the eigenvalues of an
 Hanowa matrix.
