En lille matlab Fuzzy problem

hvordan laver man en directory i matlab hvis man har en .m file i denne opgave er pendulum.m  kig opgaven nedenfor

All questions relate to the software simulator
PENDULUM. The following questions assume the
default settings in PENDULUM (see file pendulum.m).

Please do the following:

1. Start Matlab

2. Go to your PENDULUM directory: type on the
Matlab command line

>> cd path\pendulum
**** når jeg taster cd path\pendulum får jeg fejlmeddelse der siger at directory eksistere ikke. selvom jeg har lavet stien øverste i matlab skærm der ser sådan ud C:\MATLAB701\work\path og inde i path er der lagt pendulum.m filen.

The >> is a Matlab prompt, and 'path' is the path
to your pendulum directory.

3. Type 'pendulum' - now you should see the main
window of the simulator.

4. Click the Cart Results menu on the top bar.

5. Click on Cart Position. A graph window opens
and you can study the transient response of the
cart position.
