How to fix "cell contents assignment to a non-cell array object" error?

    for z=1:10;
    w=blabla;
        m=1;
        for i=1:length(new{z});
            for j=1:4;
                new[z+1]{m}.x1=rand(w);
                new[z+1]{m}.x2=rand(w);
              m=m+1;

Not sure what you are trying to do here. tr is a cell array:

tr={1,2,3,4,5,6}

So accessing the contents of tr would either be with curly braces { } to get at the contents of the cell(s), or with parentheses ( ) to get at a subset of the cell array. I.e.,

tr{1} is the double scalar 1.0
tr(1) is a 1x1 cell array whose only element contains a double scalar with value 1.0

So what is this notation supposed to do for you:

tr[t+1]{k}.wind=rand;

You've got square brackets [ ] used inappropriately, as well as using the .wind notation to indicate that you are working with a structure, which you are not. Can you explain in more detail what you are trying to do here, and what the resulting cell array or structure is supposed to look like?
