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.
