MATLAB Programming/Loglog

Introduction
The loglog command plots both x and y data sets on a log scale while the plot command plots both axes on linear scales and the semilogx/y command plots 1 axis on a linear scale and the other axis on a log scale. Other than the scale of the axes, the 3 plotting commands are identical in most ways.

Basic Usage
The basic usage of the plot, semilogx/y, and loglog command are identical. Below is an example of how a PSD would be plotted
