Like this, if necessary.
% set up parameters and use them
max_k = 12;
min_input=0;
max_input=20;
nisbad = true;
while nisbad
% explain the inputs to the user
% nobody can guess what the limits are unless you tell them
disp('Which multiplication table?');
n=input(sprintf('Please enter number from %d to %d: ',min_input,max_input));
nisbad = n<min_input || n>max_input;
end
for k = 1:max_k
fprintf('%dx%d=%d \n',n,k,n*k);
end
I could say something about this style of bad design taught by introductory assignments, but I've said it enough times to know that it doesn't matter.
