fprintf('%d+', m:n-1);
fprintf('%d = %d\n', n, TheTotal)
You definitely need to fix your vec array, whatever it is for. You are currently constructing a multidimensional array, such as zeros(2,3,4,5) for the case 2:5
Using 'sum' as the name of a variable is not recommended; it is quite common to try to use 'sum' as a variable name and then in the same code segment, try to call sum() as a function.

@Mubashir Ali: We had multiple questions in the forum concerning the redefinition of "sum" as a variable:
% Hidden in another script:
sum = rand(1, 10);
...
sum(1:100) % Why is this not working?
So better avoid using names of built-in function as variables. Use e.g. "s" instead.

This is a homework question, but you have shown an almost working code already. I only clean it up a little bit:
m = input('from:');
n = input('to:');
if m>n
error('Invalid numbers'); % not DISP: Never proceed after an error!
end
% vec=zeros(m:n); % Neither needed, but better: vec = zeros(m-n, 1);
fprintf('result is:\n');
s = 0;
for i = m:n
s = s + i;
if i < n
fprintf('%d + ', i);
else % In the last iteration display the result also:
fprintf('%d = %d\n', i, s);
end
end
