Hello guys,

How can I combine string and number elements in one matrix or cell array and how can I manipulate the data after that? Thanks :)

As Rik pointed out, your request is vague, but maybe this will get you started.

You must use a cell array to combine numbers and strings in the same variable.

Here's an example

 bg = { 3 5 9; 'Sofia', 'Plovdiv', 'Burgas'}'
 bg =
  3×2 cell array
    {[3]}    {'Sofia'  }
    {[5]}    {'Plovdiv'}
    {[9]}    {'Burgas' }

There's lots of ways to interact with this cell array (ie, 'manipulate the data').

Take the mean of column 1

mean([bg{:}])

Find the value in column 1 associated with whatever row contains 'Burgas' in column 2

bg{strcmp(bg(:,2), 'Burgas'), 1}

Get the data in the 2nd row, 1st column

bg(2,1)   %the result is another cell (1 element)
bg{2,1}   %the result is a matrix (1 element)

If there's something more specific you'd like to know, describe it in the comment section.
