How to use nested for loops?
显示 更早的评论
I am very new to MATLAB, and I have been trying to figure out how to use nested for loops correctly. I want to print out :
1
121
12321
1234321
123454321
what should I do if there are a varying number of columns? Any help would be greatly appreciated.

for variable = something : something_else
for another_variable = thing2 : thing3
% do something involving variable and another_variable
end
end

No need for nested for loops. Try this:
i=1;n=5;
while i<=n
fprintf('%d',[1:i-1 i:-1:1]);
fprintf('\n');
i=i+1;
end

... This was a homework question. It has come up before as a homework question.

There is nothing mentioned in the question that it is a homework.

Of course you can, but isn't this one simpler?

n=5;
for j=1:n
for i=1:j
end
fprintf('%d',[1:i-1 i:-1:1]);
fprintf('\n');
end
