CGLOGGEN
This function creates an evenly spaced vector of points in log space.

Returns

A vector of values, evenly spaced along a log axis.

Params

numpts: in, optional, type=integer, default=10
The number of points desired in the output vector.

Keywords

double: in, optional, type=boolean, default=0
Set this keyword to return the values as double precision values.
Otherwise, floating point values are returned.
finish: in, optional, type=float/double, default=100
The ending value of the vector. The output values are evenly spaced
between `Start` and `Finish`. This value must be a positive number.
start: in, optional, type=float/double, default=1
The starting value of the vector. The output values are evenly spaced
between `Start` and `Finish`. This value must be a positive number.

Examples

To create 10 values evenly spaced between 5 and 15::
points = cgLogGen(10, Start=5, Finish=150)
cgPlot, points, PSym=2, /YLog
