How to construct a cell of arrays from an array of arrays?

Dear all,

I have the following code, and I want to make a cell of arrays from an array of arrays, but I have an error.

The Code:

clc

clear all

close all

for i=1:2

        p{i}=[2^i-1 2^(i)];

end

p

Cell={};

for i =1:max(size(p))

    Cell(1,i)=p{i};

end

Cell

The error:

??? Conversion to cell from double is not possible.

Error in ==> Untitled5 at 11

    Cell(1,i)=p{i};

You’re almost there!

Use:

Cell{i}=p{i};

instead, and it works.

You'd be better off dealing with a regular 2D array. Why mess around with the complications of a cell array when you don't have to.

Even if you did want to have a cell array that was a copy of p, you could just avoid the loop in the first place and just do

Cell = p;

since you're simply setting the ith cell of Cell to the ith cell of p. Though, again, a regular 2D non-cell numerical array will be the simplest by far and you never have to worry about whether to use braces or parentheses or brackets.

By the way, you can use length(p) instead of max(size(p)). And it might not be a good idea to call your cell array Cell. One typo and it becomes cell which is a built-in function.

Thank you Image Analyst for your advice, I just saw what you were talking about in my second question:

The reason why I am using a cell array is that I have a variable number of raw arrays and with variable sizes, so that the 2D array wont be helpful.
