How to produce a series of strings?

I want to produce a matrix of strings. Columns are marked as numbers (0 1 2 3 4 ...) and rows as letters (A B C D ...) the matrix shows as: [A0, A1, A2, A3, ...; B0, B1, B2, B3, ...; C0, C1, ....; ....] How should I done it?

string(('A':'E')')+(1:5)

Nice. Can you get the web team to explain this capability on the website? It's not obvious from the doc and seems like a commonly used feature.

https://www.mathworks.com/help/matlab/ref/colon.html

EXAMPLE: Create an Alphabetical Char Array
   'a':'z'     all a-z lower case
   'A':'Z'     all A-Z upper case
   'A':2:'Z'   every other upper case letter

EXAMPLE: Create a String Matrix
   string(('a':'z')') + (1:3)

Hi Ocder,

I can, but it would actually sound better and be more likely to be acted on coming from you(!). File a simple tech support enhancement request through the support center or MATLAB desktop with your wishes. Dev/Doc is more likely to listen to customers than pesky application engineers :)

Haha. Sounds fair. I'll go ahead and send in a request.

STR = strings(10, 10);
for r = 1:10
    for c = 1:10
        STR(r, c) = string(char(('A'+r-1))) + (c-1);
    end
end
