linspace
generates linearly spaced numbers between 2 reached bounds
Syntax
row = linspace(x1, x2) row = linspace(x1, x2, n) Matrix = linspace(Col1, Col2) Matrix = linspace(Col1, Col2, n)
Arguments
- x1, x2
Real or complex scalars: Bounds between which values must be generated.
- Col1, Col2
Column vectors of same heights of real or complex numbers.
- n
integer number of requested values or columns. Default value: 100
- row
row vector of
n
numbers.- Matrix
Matrix with
n
columns of numbers.
Description
linspace(x1, x2)
generates a row vector of n
equally spaced
values ranging exactly from x1
to x2
.
The syntax Instead of fixing the step to a given value, |
If x1
or x2
are complex numbers,
then linspace(x1,x2)
interpolates separately the real and
the imaginary parts of x1
and x2
.
If some column vectors Col1
and Col2
are provided, linspace
works in a row-wise way:
the resulting Matrix
has the same number of rows,
and n
columns. We get
Matrix(i,:) = linspace(Col1(i), Col2(i), n)
.
Examples
linspace(1, %pi, 0) // n = 0 linspace(1, 2, 10) // x2 > x1 : increasing values linspace(2, 1, 10) // x2 < x1 : decreasing values linspace(1+%i, 2-2*%i, 5) // with complex numbers linspace([1:4]', [5:8]', 10) // with input columns
--> linspace(1, %pi, 0) // n = 0 ans = [] --> linspace(1, 2, 10) // x2 > x1 : increasing values ans = 1. 1.111 1.222 1.333 1.444 1.556 1.667 1.778 1.889 2. --> linspace(2, 1, 10) // x2 < x1 : decreasing values ans = 2. 1.889 1.778 1.667 1.556 1.444 1.333 1.222 1.111 1. --> linspace(1+%i, 2-2*%i, 5) // with complex numbers ans = 1. +i 1.25 +0.25i 1.5 -0.5i 1.75 -1.25i 2. -2.i --> linspace([1:4]', [5:8]', 10) // with input columns ans = 1. 1.444 1.889 2.333 2.778 3.222 3.667 4.111 4.556 5. 2. 2.444 2.889 3.333 3.778 4.222 4.667 5.111 5.556 6. 3. 3.444 3.889 4.333 4.778 5.222 5.667 6.111 6.556 7. 4. 4.444 4.889 5.333 5.778 6.222 6.667 7.111 7.556 8.
