I an performing dualtree transform,i have completed dual tree performed some operation and i have 10 matrices in each variable,now i f
for j = 1:J
for s1 = 1:2
for s2 = 1:3
a1{j}{s1}{s2}=a1;
end
end
end
if i use a1{j}{s1}{s2} i get error as
Cell contents assignment to a non-cell array object.
Error in ==> ssample at 35
a1{j}{s1}{s2}=a1;
if i use
w1{j}{s1}{s2}=a1;
the size of a1 is {1x2} {1x2},w1 is {1x2}
if i use
w{j}{s1}{s2}=a1;
i get correct answer as
{1x2} {1x2}
i want to store in different variables in order to perform idualtree ,please help

Are you really sure, that you need a cell of cells of cells? This is possible, but not common. Would a [j, s1, s2} cell satisfy your needs?

Examine
a1{j}{s1}{s2}=a1
Notice that you have the same variable name on the left and right hand side, so you are attempting to store a copy of the entire cell array into an element of the cell array. Are you sure that is what you want?

In what you described in your Question, you get the error when you try to store a1 in to part of a1, and you do not get the error when you store a1 in to part of some other variable. That is the opposite of what you describe now, in which you say you get an error if you "store in another variable".
At least one of us is confused.
