logspace - Generate logarithmically spaced vectors
Syntax
y = logspace(a,b)
y = logspace(a,b,n)
y = logspace(a,pi)
Description
The logspace function generates logarithmically
spaced vectors. Especially useful for creating frequency vectors, it is a
logarithmic equivalent of linspace and the ":"
or colon operator.
y = logspace(a,b) generates a row
vector y of 50 logarithmically spaced points between decades 10^a and 10^b.
y = logspace(a,b,n) generates n points
between decades 10^a and 10^b.
y = logspace(a,pi) generates the
points between 10^a and pi, which is
useful for digital signal processing where frequencies over this interval
go around the unit circle.
Remarks
All the arguments to logspace must be scalars.
