Is it possible to put a character into a matrix?

I'm trying to do this

m1 = [1, 2, 3, 4, 5, 6, 7];

m2 = 'A';

m1(3) = m2;

so that m1 will be

[1, 2, A, 4, 5, 6, 7]

Instead of what I actually get.

[1, 2, 65, 4, 5, 6, 7]

You'd have to use a cell array. I couldn't figure out how to get cell2mat() to work, so I used a for loop:

m1 = [1, 2, 3, 4, 5, 6, 7];
m2 = 'A';
for k = 1 : length(m1)
  m3{k} = m1(k);
end
% m3 = mat2cell(m1, ones(1, 7)) %, ones(1, length(m1)), numel(m1))
celldisp(m3)
% Now replace third element with a character.
m3{3} = m2;
celldisp(m3)

You cannot mix numeric and character values in a numeric array. You can do it with a cell array, but it’s only good for storing the values. You would encounter the same problem if you wanted to calculate with it.
