How to Create Equally Spaced Row Vectors in MATLAB
Method
linspace(a,b,n): Returns a row vector of $[a,b]$ divided into $n$ equal intervals.
If the number of elements is not specified, it returns a $1\times 100$ vector. It is used when the number of intervals is important, not the length of the intervals.
a: m :b: Returns a row vector of $[a,b]$ divided by equal intervals of $m$.
If the interval is not specified, the interval is set to $1$. It is used when the length of the interval is important, not the number of intervals. There may not be a natural number $n$ that satisfies $b=a+n\cdot m$. In this case, the endpoint is not $b$, but the largest number satisfying $a+n\cdot m$.
x1=linspace(1,10,10)
x2=linspace(1,10)
x3=linspace(5,55,2^5)
y1=1:3
y2=1:1/13:2
y3=3:1/7:7
