linspace

Creating a row vector with equally-spaced entries

Usages

linspace(a, b, n)

• a and b should be real or complex scalars.
• n should be real non-negative integer scalar not equal to Inf nor NaN.
• a, b and n should be non-empty.
• It returns a row vector of n equally spaced elements starting with a and ending with b.
• That means, it returns the vector $\begin{bmatrix}a&a+d&\cdots&a+(n-1)d\end{bmatrix}$, where the spacing is defined as $d=(b-a)/(n-1)$ for $n\geq 2$.
• It returns b if n == 1.
• It returns an empty matrix if n <= 0.

linspace(a, b)

• It returns the same result as linspace(a, b, 100).
