I need to create a matrix using the vectorized blocks as columns. This H matrix is needed for compressive video sensing given by azghani as "multihypothesis compressed video sensing".

Given columns A,B,C etc just put them together
H=[A,B,C]
To do it programmatically, save you columns in a cell and then invoke cell2mat:
%you might do this in a simple for loop
C={A,B,C,..}
%get your matrix
H=cell2mat(C);

Note: in the compatibility section of the R2016b release notes, there is a warning that in future C{:} will only work for vector C .

Hum, I can't see that. Which section is it under exactly?
That would also make absolutely no sense to me. Just as (:) reshape into one column, {:} should reshape as one comma-separated list.
