y = linspace(-L,L,(N+1))
why this is not working even though it meets all the requirements in the assert?

I have the same question. Would anyone kindly help us? Thank you.

I am also wondering why linspace(-L,L,N+1) is not working. It passes the last test suite, but fails the first two.

Lee Chih Jung on 12 Oct 2020

It's coz the test suite only accounts for whole numbers, so you're going to have to do something else to the numbers within the vector generated.

I'm not sure what is a real difference between linspace and : operator.

y = linspace(-L,L,N)
It strangely does not work

Anirban Pal on 16 Apr 2020

linspace doesn't work as it gives a std(diff(y)) of the order of 1e-15 and not 0.
Use colon operators.
