Matlab Zoom Feature
Zooming is essential to find the exact frequency of a
signal. For the purposes of this website, the frequencies will be located
from 0 to 1000 Hz. When a Matlab plot window appears the range may be on
the order of 20,000 Hz. This will inhibit us from locating the exact
frequency of the wave file we are analyzing.
There are two ways that you can zoom in a Matlab plot
window:
1. Click the +magnifying
glass and drag the mouse over the plot of the area that we want to see.
2. Go to edit then axes properties
and uncheck the auto for the x axes and
change the upper bound to 1000 Hz for
example. Now click ok and your plot has changed to something more
manageable. This process can be repeated to zoom in or out to see the
desired frequency range based on the characteristics of the signal.
