What is the difference between linspace and the colon operator in this code?

Hi! What is the difference between the linspace function and the colon operator in this code?

v1 = (0:1/200:1);
v2 = linspace(0,1,200);
>> v1==v2
Matrix dimensions must agree.

Why is there one element more in v1 than in v2?

Thank you very much Timo

Because the interval between the elements of v2 is not 1/200. It's 1/199.

>> isequal(v2(2)-v2(1),1/199)

ans =

     1

That is the separation needed to get 200 equally spaced points.
