logspace — Logarithmically spaced vector

$\begin{rail} Logspace : 'logspace' '(' Scalar ',' Scalar ( ',' Scalar)? ')' ; \end{rail}$
logspace creates a vector of logarithmically spaced points. If the first two arguments are x₁ and x₂, then the points are generated between 10^x₁ and 10^x₂. If the optional third argument is present, it specifies how many points are to be created. If the third argument is missing, then 50 points are assumed. As a special case, if the second argument is equal to π, then the points are generated between 10^x₁ and π. $\Longrightarrow$ This is not an built-in function. This function is normally loaded on start-up from the logspace.r file in the standard rlib directory. Use of the -r option, incorrectly setting the RLAB_LIB_DIR environmental variable, or modifying logspace.r may make this function unavailable.
