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