What is the relation between A and B?
Why for .2 there is 5 values and for 0.15 there is 6?

a = [0.25 0.20 0.15 0.20 0.1];
your_mat = cell2mat(arrayfun(@(x,y) ((x:x:1)'+y)',a,0:numel(a)-1,'uniformoutput',false));
your_mat = [0;your_mat'];

A=[0.25 0.2 .15 .2 .1]
a=cell2mat(arrayfun(@(x) x+A(x)-1:A(x):x,1:numel(A),'un', 0 ))'
