An
icon link for MATLAB should be available on the Desktop of each computer in a
CNC lab. Across campus, you may have to page throught the START menu and into
PROGRAMS before you find a link to the executable. Either
way, once you launch the package something close to the following should
appear: Note the command line
prompt “>>” It is from this command
line you will issue all MATLAB commands. MATLAB is a command interpreter NOT
a high level programming language. However, you can write “programs” that are
more correctly called “scripts” or “.m” files because a file with a “.m”
extension will often be recognized as a MATLAB script. These scripts are in
many ways like macros you may have composed using Excel or a similar spreadsheet
program. To get started, type each
commands one at a time from the command window: helpwin, helpdesk and demo.
After entering each command, spend some time reading JUST the INTRODUCTORY
materials Here, we are going to get
you started by looking at the demo
option: >> demo As you proceed with your
reading you will see there are actually many different demos, all accessible
from a demo window that is popped up when you type "demo" at the
command prompt. You are not really expected to learn the details of using
MATLAB through these demos, but rather just to get a good feel for all the
kinds of things you can use MATLAB for. There are even some games you can
play in these demos, and most of the demos have quite visually appealing
graphics, so you should enjoy going through these demos. Again, don't stress
out about trying to understand details, but just try to get an overall feel
for what kind of a tool MATLAB is, what kinds of problems you can use it for,
and generally how you use it. MATLAB is a very practical and powerful tool
for solving many different types of problems, and you should appreciate this
more after going through some of the demos. So, to start the MATLAB
demos type "demo" at the command prompt and then hit the enter key.
The MATLAB demo window should then pop up and wait for you to choose and run
the various demos; the MATLAB demo window looks like this: We won't go through all
the demos here in this tutorial, but rather get you going by showing you how
to start one of them. You can then work through some of the others similarly
at your own pace. Anyway, the text box at
the left (i.e., the one labeled “ But you also see a lot of
commands that look like this:
These are the individual
“commands” that will create this image. In fact, if you copy and paste ALL of
these commands into the command window and release them at the command prompt
“>>” you will generate a graph very much like you see above. This is a
GREAT way to learn how many commonly used MATLAB command work and what
options you have for using them. To continue on to the
