s='A':'J'
str=s(randi(numel(s)))

Do you want capital or lower case letters? You can just use the ascii representations

char(97:106)

or

 char(65:74)

If you have the Statistics Toolbox you can randomly sample from those "populations"

 idx = randsample(65:74,5); %choose five letters at random
 char(idx)

AB

AC

AD

AE

AF

let these be the options to randomly generate...how can i do that?

I suggest asking as a new question and linking to this post, but I wouldn't be surprised if this question has been asked already somewhere.

it is the function that can generate random alphabet between the given alphabet.. one more thing you can also input the ascii code of alphabet

function ra=randa(a,b)
%a=any number or alphabet 
%b=any number or alphabet
l=double(a);
k=double(b);
if a>=65&b<=90
   ra=char(randi([l k],1,1));
elseif a>=95&b<=122
   ra=char(randi([l k],1,1));
else
    error('you are entering wrong number or alphabet');
end
end

Your ranges are off

char(60:90)       %what you use

ans = '<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ'

('A':'Z')+0       %actual

ans = 1×26

65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90

Your use of > and < is confusing. Use >= and <=
