Matlab is a high-level computer programming language geared for rapid scientific and technical computing. It is used widely throughout industry and academia. I am a major proponent of Matlab. I have been using it for years and think it’s a great programming language for algorithm development, hardware control, and general scientific programming. Because it is relatively easy to learn, it is a great programming language to introduce students to general programming concepts and algorithm development.
This is where you can find example code used in the various projects that are found on the Projects page.
Data Acquisition Control Software
A simple GUI used for controlling data collection with the NI-USB 6009 data acquisition device.
Matlab source code: DAQ_Control_Simple_GUI
Matlab executable: DAQ Control Simple Installer
NI Drivers: NI-DAQ
You will need to have Matlab installed on your computer as well as the Data Acquisition Toolbox and the NI-DAQ drivers in order to run the source code. You will also need to install the NI-DAQ drivers for the compiled version of the code, DAQ Control Simple Installer. Below shows a screen shot of the GUI and outlines the basic operation. I have implemented some basic error handling, but I can’t guarantee I covered every scenario. If you come across any bugs, post a message.
Data Acquisition Control GUI for NI USB-6009 DAQ
The figure below shows an output plot from the DAQ GUI. You can use the Save Data button to save data in the plot as a .mat or as a text csv file.
Example plot from DAQ GUI. Data was for a hand moving in front of 10.52GHz RF Sensor. The Save Data button is used to save data in plot as a .mat file as a .csv file

Radar Explorer Software
Software for exploring FMCW type radar and the use of FFT’s to convert frequency domain data into range data. Below you can find the Matlab source code for the GUI (Radar Explorer Source), as well as a compiled version (Radar Explorer Exe).
Radar Explorer Application for Investigating FMCW radar signals and the use of FFTs
Example data output from Radar Explorer. Plot on left shows I & Q (freqeuncy data) outputs of a radar sensor with two targets in the field of view. The right plots shows range data, determined by applying an FFT to the I&Q data and then applying the appropriate axis scaling.
Sivers Radar Control Software
Software for communicating with the Sivers radar evaluation board. Can be used to set various board parameters and collect and save data. Download executable software here siversRadarControl_installer_v1.

Ali,
are you trying to run the compiled code or the un-compiled code? If you are running the uncompiled code, could you type ver at the matlab command line and send me the output?
thanks

hi,
I use matlab 2010 windows 7 32 bit ,when I type the ver command it appears:
>> ver

Ali,
I believe that you are getting that error because you are using Matlab Version R2010a. The code I wrote uses the Session Based Interface which is support on Matlab version 2011+. If you can update your version of Matlab, this will solve the problem. Or you can run the compiled version, which you can download from the same place you found the code. Or, if you can wait a few days I can rewrite the code using the Legacy mode, which would allow it work with your version of Matlab.

hi,
Now I use matlab 2011.,
the problem is the following,
when I drive supports the button Locate DAQ Device, it displays a dialog box
“no daq device found”,
when I tappes the following command on the command line:
hdaq=daq.getDevices
it appears:
No data acquisition devices available.
