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

beginnerMATLAB

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 =
    logical
     1
That is the separation needed to get 200 equally spaced points.
