_______BEGINING OF CODE___________________
n=0
while n<5 || n>25
n=input('please enter a value 5<n<25---');
if n<5 || n>25
disp('the value isnt vaild,try again');
end
end
array=round(100*rand(n,n))
total_sum=0;
________END OF CODE________________
so basically if I wanted to find the sum of say row 2, how can I declare row 2 as B? so that row "n" can be the equivalent of its place in the alphabet.. example Row1=a Row2=b Row3=c exc... and column1=aa column2=bb exc..

I'm just stating my opinion here. But, do you really need to name the rows and columns as specific variables? Isn't it more efficient to just use the index? For example, if you want the user to input which row they are interested in finding the sum of, then:
sum(array(k,:)) % where k is any number indicating the row
