Image acquisition command "imaqhwinfo" is not getting recognized in matlab.

So,I tried connecting this camera http://www.amscope.com/3mp-usb2-0-microscope-digital-camera-software.html to my computer and then tried running the command imaqhwinfo and it gives the error "Undefined function or variable".Why it is doing so?

P.S-The camera is working fine otherwise,I have even captured images with its help.

Which MATLAB version are you using? Do you have the image acquisition toolbox installed and licensed?

Have you googled it? Lot of links discussing this error and solution.

@walter..I am using R2014a and I guess it must be having the image acquisition toolbox license as I get to use it by IIT,Kanpur,India.

@kssv..Yep I googled,it there is another command "which -all imaqhwinfo",I found it in suggestion and it also gave me an error "Not Found".

You do not have the Image Acquisition Toolbox installed, or else your installation is corrupt.

It has started recognizing the command imaqhwinfo after I got another version of matlab but somehow it is still not recognizing my camera.What to do for that?

P.S-Sorry for replying late,I wasn't well.

You might need to install a support package,

I am gonna try it now.Will update soon.

Matlab USB support package is not available for 2013a ? It doesn't show here- https://in.mathworks.com/hardware-support/system-requirements.html

[Walter Roberson]

Earlier you said you were using R2014a. https://www.mathworks.com/matlabcentral/fileexchange/45182-matlab-support-package-for-usb-webcams starts from R2014a

You might perhaps be able to use https://www.mathworks.com/matlabcentral/fileexchange/43306-simulink-real-time-support-package-for-usb-video in R2013a, but that does say Simulink

[Prachi Sharma]

Yes,I was using R2014a but you told me that image acquisition tool must be there so I uninstalled it because that one didn't have the license for image acquisition.I have 2013a now.I guess I need to have 2014a or above along with image acquisition toolbox.
