MATLAB: Dynamic vectors into cell

Question

Hi!

I have 3 vectors (here A,B and C) that could have diferent size (are dynamics, size is not define) and i need to make a cell like "MyCorrectData" where the last column ist logical.

A=[1 1 1]
B=[2 2 2]
C=logical([1 0 1])
MyCorrectData={1 2 true; 1 2 false; 1 2 true}; %this is what i want

This works almost fine, but the last column lost the type and convert in double

A=[1 1 1]
B=[2 2 2]
C=logical([1 0 1])
MyCorrectData={1 2 true; 1 2 false; 1 2 true}; %this is what i want
MyData=[A B C]
MyData=num2cell(MyData)

How can i solve this?

Thanks!

It is very easy to get what you want, you just need to avoid concatenating all of the numeric/logical data together, e.g.:

>> D = [num2cell(A(:)),num2cell(B(:)),num2cell(C(:))]
D = 
    [1]    [2]    [1]
    [1]    [2]    [0]
    [1]    [2]    [1]

And checking:

>> MyCorrectData={1 2 true; 1 2 false; 1 2 true}; %this is what i want
>> isequal(D,MyCorrectData)
ans =
     1

For an arbitrary number of arrays just put them into the cell array first, e.g.:

>> D = {A,B,C}; % any number of suitably-sized arrays.
>> D = cellfun(@(a)num2cell(a(:)),D,'uni',0);
>> D = [D{:}] % horzcat
D = 
    [1]    [2]    [1]
    [1]    [2]    [0]
    [1]    [2]    [1]
