# logspace

## Purpose

Generate logarithmically spaced vectors.

## Synopsis

    y = logspace(a,b)
    y = logspace(a,b,n)
    y = logspace(a,pi)

## Description

`logspace` 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`.

`logspace(a,b,n)` generates `n` points.

`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.
