Dear Rxperts,
Can "Jordan decomposition" of submatrices be useful to determine size of sub
blocks? "http://en.wikipedia.org/wiki/Jordan_normal_form";..
Thanks for the ideas/suggestions.
.
I have another similar situation, where at least one of the off diagonal
elements of the lower triangle subma
Thanks, David! That is another interesting perspective to (sub/super)
diagonal story! For now I was looking only at block sizes of lower triangle
submatrices as Dennis suggested.
Regards,
Santosh

Dear Rxperts
Below is a small vector of values of zeros and non-zeros... was wondering if
there is an efficient way to get the block sizes of submatrices of a big
matrix similar to the one shown below? diagonal elements can be zero too.
Rows with only a diagonal element may be considered as a unit
