These functions are as follows: “xlim ()” Function - The “xlim ()” function is used to adjust X-axis limit of a plot in MATLAB. “ylim ()” Function - The “ylim ()” function is used to adjust Y-axis limit of a plot in MATLAB. By default, the cartesian axes are added to a figure in MATLAB when it is created as a graphical component however, MATLAB provides a function to do the particular job, the axes() function. This function creates cartesian axes in a figure. It is highly useful in cases where multiple cartesian planes are needed in a single figure component.

In a function file which contains only function definitions. The name of the file must match the name of the first function in the file. In a script file which contains commands and function definitions. Functions must be at the end of the file. Script files cannot have the same name as a function in the file.

If you want the axes to choose the appropriate limits, set the limits mode back to automatic. axis auto.You may subtract the magnitude of those values which are greater than 40 and less than -40 by the length of the gap. That means the actual values are deducted and hence the XTick corresponds to [-80 80] only for example, while manually edit the XTickLabel to [-100 100].F = getframe (fig) captures the figure identified by fig. Specify a figure if you want to capture the entire interior of the figure window, including the axes title, labels, and tick marks.
