SEMILOGY Semilog Y Axis Plot Function

Section: Handle-Based Graphics

Usage

This command has the exact same syntax as the plot command: 
  semilogy(<data 1>,{linespec 1},<data 2>,{linespec 2}...,properties...)

in fact, it is a simple wrapper around plot that sets the y axis to have a logarithmic scale.

Example

Here is an example of an exponential signal plotted first on a linear plot: 
--> x = linspace(0,2);
--> y = 10.0.^x;
--> plot(x,y,'r-');

and now with a logarithmic y axis 

--> semilogy(x,y,'r-');
