The steps for installing the MATLAB files to accompany the text “Signals and Systems – A MATLAB Integrated Approach” are explained below.
Installation instructions can also be downloaded as a pdf file by navigating to the
downloads page.
-
Download the current version of the archived file “SigSys_MATLAB_v1_##.zip” from the downloads page.
-
Uncompress the archive “SigSys_MATLAB_v1_##.zip” to a directory such as “C:\SigSys”.
-
Start MATLAB.
In the command window, type the following:
>> pathtool
-
This starts the MATLAB “Set Path” dialog, as shown below.
-
Click the button “Add with Subfolders…”. This brings up the “Browse For Folder” dialog shown below:
-
Navigate through the directory structure to find the directory where the archive was uncompressed, for example “C:\SigSys”, and select it.
Click the “OK” button to close the “Browse For Folder” dialog.
(If the files have been extracted into directory different from “C:\SigSys”, adjust this step accordingly.)
-
Click the “Save” button to close the “Set Path” dialog.
-
Now the MATLAB files are ready to be used.
To run one of the GUI-based interactive demo programs, type its name in the command window. For example, the command
>> conv_demo1
starts the program referred to on Page 149 of the text.
The command
>> ex_2_21
runs the script file associated with Example 2.21 on Page 149 of the text.
-
It is also possible to incorporate the software with MATLAB help system so that all scripts and interactive demo programs
can be accessed easily through a menu system arranged by chapters.
To accomplish this, click on the “Help” icon on the MATLAB toolbar as shown below:
-
Click on “Supplemental Software”.
