Hi,

I am wondering if there is a way to enter the contents of a cell array into another array. I need this to be something I can do for cell arrays with contents that are of varying sizes. Let me give an example of what I mean. Let's say I have the following pre-made cell array

A={[1 3],[],[2 3 7 8];[2 4 5 7],[4 7 8],[];[],[],[]}

and now let's say I have the follow non-cell array

B=[0 0 5;0 3 0; 3 9 2]

Let's say I want to take A and everywhere in B where this is a zero, replace it with the corresponding location in A. So it would look like this

C=[[1 3],[],5;[2 4 5 7],3,[],3,9,2]

I am confused as to how or if I can do this. I know I can't just convert A to a non-cell array since each of the components of it are not the same size.

在 MATLAB Online 中打开

Bc = num2cell(B);
t = B ~= 0;
C = A;
C(t) = Bc(t);

Hi Andrei,

Thank you for submitting a response to my question. I see that you converted the non-cell array to a cell array and the combined the two arrays together. I am concerned that this will not meet my needs though as I have a figure with a grid and I need to be able to display each component of the array on the grid in a different box. I know how to do this with a non-cell array. Is it possible to combine the two arrays without having to convert the A array to a cell array before combining or do you know of the necessary syntax to be able to display the now cell-array onto a grid figure? I'm sorry if this explanation doesn't exactly make sense and I would be more than willing to try and explain it differently.
