MATLAB For Dummies

Appendix A

MATLAB Functions

This appendix provides you with an overview of the MATLAB functions. Each function helps you perform a specific task within MATLAB. The tables contain the function name and a short description of the task that the function performs. If you need more information than this appendix gives you, you can obtain additional information by typing help <function_name> in the MATLAB command window and pressing Enter. Of course, you also have the information found in this book, and you can search in Help. See Chapter 3 for some useful information on using the Help resources that MATLAB provides.
