matlab中zoom和pan函数的使用方法 ，举例说明

Sure, I'd be happy to help!

The zoom function in MATLAB is used to zoom in or out on a plot. To use it, simply click and drag the mouse over the area you want to zoom in on. To zoom out, click and drag over the area you want to zoom out from while holding the Alt key.

The pan function in MATLAB is used to move around a plotted image. To use it, simply click and drag the mouse over the image to move it in any direction.

For example, if you have a plotted signal and want to zoom in on a specific section, you can use the zoom function to select that portion of the signal and then use the pan function to move around within that selected section. This can be helpful for analyzing specific parts of the signal or for examining multiple signals simultaneously.
