1.3 Help in MATLAB
MATLAB help through the help button in the toolbar can be accessed here or through the Help menu bar option.
In addition, support can also be obtained through commands implemented as MATLAB objects. The command help
provides general help on all commands in MATLAB (Figure 1-15 ). By clicking on any of them, you get your particular
help. For example, if you click on the hyperlink graph2d , you get support for graphics in two dimensions (Figure 1-16 ).
