Matrix consist of letters

Hello.

I really want to know if it is possible to fill a matrix with x,y and z.

Here is my attempt so far:

 >> X=zeros(3,10)

X =

       0     0     0     0     0     0     0     0     0     0
       0     0     0     0     0     0     0     0     0     0
       0     0     0     0     0     0     0     0     0     0

>> X(1,:)=[1 :10]

X =

     1     2     3     4     5     6     7     8     9    10
     0     0     0     0     0     0     0     0     0     0
     0     0     0     0     0     0     0     0     0     0

I have succeed to fill the first row with number, from 1 to 10. But, what if I want to fill the first rows with only letters, just 'x' in the first row, is that possible?

I would be very happy if someone can help me and answer on my question.

Best Regards

Cillian

What you have is a matrix of doubles. Letters would be chars and you cannot mix them together unless you use cell arrays.

Before showing how would you go about with a cell array, what do you need this type of "matrix" for?

Do you want something like this

X = [repmat('x', 1, 10); repmat('y', 1, 10); repmat('z', 1, 10)]

Or maybe this makes more sense

X = zeros(3,10);
X(2, :) = 1;
X(3, :) = 2;
X = char(X+120)

basically the characters "x", "y", and "z" have values of 120, 121, and 122.

Thanks, Daniel. That was exactly what I looking for.
