cell problem

this is my code:

zeromatrix = zero(size(vec), 1) mean(aaa) = zeromatrix

where vec is 2 million X 1 mean is a 2 by 1 cell aaa is just a counter, so in this case, it is a 1

when i try to run it, it gives me:

??? In an assignmnt A(I) = B, the number of elements in B and I must be the same

anyone have any idea how to get past this? thanks

size() returns 2 values.

mean() is a MATLAB function so not to use it as a variable name.

To assign a matrix to a cell array, you might want to use {}. A{1}=zeromatrix;

Use a small size vec to test out your code first and then make it 2 million by 1.

ok, i changed mean() to name(), because mean isnt what i wanted to use, what i wanted is have a cell to store the zeromatrix. any way to do that?

so now i have

name = cell(1,counter)

zeromatrix = zero(size(vec), 1)

name(aaa) = zeromatrix

by the way, the error now says

??? Conversion to cell from double is not possible

[Fangjun Jiang]

name = cell(1,counter)

zeromatrix = zero(size(vec))

name{aaa} = zeromatrix

thanks it worked!
