## Arguments

d1,d2

  real or complex scalar (special meaning for `%pi`)

n

  integer: number of requested values. It must be greater or equal to 2 (default value = 50)

## Description

returns a row vector of `n` logarithmically equally spaced points between 10d1 and 10d2. If d2=π then the points are between 10d1 and π.

## Examples

    logspace(1,2,10)
