Hi,
You seem to have created a MEX function and named it as "webcam". This is shadowing Webcam SPKG's function "webcam".
This is the reason why you get the error message that it needs 4 input arguments.
Rename the file name(from "webcam") to overcome the issue.
Hope this Helps!

I fully remove Matlab and the problem solved.
