m \times n \times N
array.
For
k = 1 , \ldots , N
we define
B_k \in \B{R}^{m \times n}
by
\[
B_k = Bdia(:, :, k)
\]
B
is defined by
\[
B
=
\left( \begin{array}{cccc}
B_1 & 0 & 0 & \\
0 & B_2 & 0 & 0 \\
0 & 0 & \ddots & 0 \\
& 0 & 0 & B_N
\end{array} \right)
\]
n * N

m * N
.
ckbs_blkdiag_mul
.
It returns true if ckbs_blkdiag_mul
passes the test
and false otherwise.
