I'm tring to get image data via webcam and wanna show in GUI window. However, recently I re-download neweat MATLAB version and data acquition as well.
However, I'm follwing the tutorial and 'imaqhwinfo' function didn't work. This is the saying in the command window. =============================================
imaqhwinfo Undefined function or variable 'imaqhwinfo'.
=============================================
I checked the connection of Webcam (USB), I don't know how I can check the connection of this device.
The MATLAB license no. is 690907. I look forward to hearing from you.
Thank you, YuJaung Kim

imaqhwinfo is part of image acquisition toolbox.. I'm guessing you do not have the toolbox..
try
which imaqhwinfo
It will show you if the function exists (if it does what is its path) (Your error suggest it cannot find the function)
try the ver command and see if Image Acquisition Toolbox is part of your license
ver
