I want to print the dot number that contains the text character.

clear
clc
NN = str2mat('s23;s24');
for i = 1:2
    name{i}= sprintf('%d. Point', NN(i))
end

I tried something like that but I could not do it.

For the cases i=1 and i=2 what would your desired output be?

[Muhendisleksi]

i=1 >>> s23. Point
i=2 >>> s24. Point

NN_split = strsplit(NN, ';');
for i = 1 : 2
  name{i} = sprintf('%s. Point', NN_split{i});
end

Mind you, I would not have initialized NN that way in the first place unless there was good reason to:

NN = {'s23', 's24'};
for i = 1 : 2
  name{i} = sprintf('%s. Point', NN{i]);
end

or more simply

NN = {'s23', 's24'};
name = strcat(NN, '. Point');

with no loop.
