Str to Cell (trivial ?)

Hallo there,

I would like to make out of a big string a cell array, e.g.

str1 = ['aa1','bb1','cc1'];
str2 = ['aa2','bb2','cc2'];

Edit : what I mean is a string representing various rows and columns, i.e. strMatrix = [str1 ; str2 ; strN]], which has to be converted into a cell matrix.

The question is how to make out of each comma separated string entry, seperate cell array entry. Im looking for something similar like

dataCell = {eval(str1),';', ...
             eval(str2)};

At the end I want to have the following :

dataCell = {'aa1','bb2','cc2'; 'aa2','bb2','cc2'}

Thanks in advance.

Your main problem is that once you create the strings 'str1' and 'str2' there is no way of knowing that they were originally three seperate strings, hence splitting them again becomes troublesome.

So, the only solution is

dataCell {end+1} = 'aa1';

?1?

[Daniel Shub]

What are you trying to do? Are aa1, bb1, always three characters? What is the original input that you have?

Im trying to find a performative solution for creating a cell array out of a string array.

@RubenMath: Please consider this:

['aa1', 'bb1', 'cc1'] is identical to 'aa1bb1cc1'

So your inputs are not clear yet.

what I mean is a string representing various rows and columns, i.e. strMatrix = [str1 ; str2 ; strN], which has to be converted into a cell matrix.

What about

str1 = {'aa1','bb1','cc1'};
str2 = {'aa2','bb2','cc2'};
dataCell = [str1; str2];

[Titus Edelhofer]

If the str1 and str2 are already given as cell arrays you might just write

dataCell=[str1; str2];

But I guess the main question is still: how do the original strings look like? str1 in the original question is just 'aa1bb1cc1'.

@Daniel: {str1{:};str2{:}} is less efficient than [str1; str2].

Of course it is. Thanks guys. I edited the answer.
