Generate logarithmically spaced vectors



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.


All the arguments to logspace must be scalars.
