how to creat cell array
显示 更早的评论
how to creat function which will have an input integer n. if n positive it will create and return a cell array with strings of random characters of increasing lengths from 1 to n
for example
functionname(4)
ans=
'z' 'zf' 'zfk' 'zfke'
and if it negative it will decreasing
many thanks

Your example only includes lower case so this code does as well.
function randLetters = myfunc(integer)
letters = 'a' : 'z';
rnum = randi(length(letters), 1, abs(integer));
randLetters = cell(1, abs(integer));
for i = 1:abs(integer)
randLetters{i} = letters(rnum(1:i));
end
if integer < 0
randLetters = fliplr(randLetters);
end
Example
myfunc(8)
ans =
1×8 cell array
{'r'} {'rw'} {'rwf'} {'rwfh'} {'rwfht'} {'rwfhtb'} {'rwfhtbt'} {'rwfhtbta'}
myfunc(-4)
ans =
1×4 cell array
{'whke'} {'whk'} {'wh'} {'w'}

Try again. It works for me. If you get the error again,copy and paste the entire error message here.

I just tried it again and it works with negative and positive inputs. Try copying my version of the code again and replacing whatever code you have. After I published my answer I updated it minutes later with a correction. Maybe you are working with the verion that doesn't have the correction.
If you wrote a personal message I probably didn't get it since I don't take PMs. But I'd be glad to help you here.
Also, you should edit your question and add in the example you removed so your question is complete and understood by others who read it.
