Problem 5. Triangle Numbers

i dint realize i was writing a code for sum of first n natural numbers instead of computing n*(n+1)/2

Man, this takes me back to algebra... Its more fun in MATLAB tho!

It's interesting to work with and building the confidence to solve problems....nice

Good one. Reminds me of those old school days..!!

All solutions with score 10 or 11 use the regexp cheat.

Jon or anybody!
Can you explain how the regexp cheat works?

How do you reduce the size of your code?

mucha fantasía en el titulo

what it means?

I really had to use my brain for this problem

Interesting!

sound simple but annoying

Funny and interesting problem!

good!

For clarity sake,

t = triangle (n)
We need to calculate t for a given n

It is pretty easy but tricky!

Why doesn't this work?

function t = triangle(n)
t=1
for i=[1:(n+1)]
t=t+i;
t
end

that was fun

Cool problem!

Interesting

cool

The formula makes this an easy math problem.
