Dynamic vectors into cell

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!

"MyCorrectData={1 2 true; 1 2 false; 1 2 true}; %this is what i want"

You simply can't mix data types in an array; you can have a cell array in which different elements in the cells contain differing data types, but not in a single cell.

About closest you could come to your above would be

M={[1 1 1];
   [2 2 2];
  logical([1 0 1])};

yields

>> M
M =
  3×1 cell array
    {1×3 double }
    {1×3 double }
    {1×3 logical}
>>

Thanks for the answer!!

And how can i manage a table(from the GUI) with 2 columns of numbers and 1 column of logical data?

Columns of tables can be of differing types...you just store what you want.

Never used the uitable in anger, dunno if it will allow cell input by table cell to mix random types or not. The table class must be the same type for the column if not a cell but will allow a cell so can mix. Generally if do so it gets much more difficult to write generic code, however, as then have to handle the cells differently depending upon content.

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]

Thank you!!!!

This works fine!!!!!!!!
