I am connecting my raspberry pi2 to matlab in order to do some image processing. However, when I run the following commands all I get is a black screen. I know the issue is not the camera because I tested it on the pi os and it gives me pictures just fine. Please help.
The code is:
mypi=raspi();
myCam=cameraboard(mypi,'Resolution', '640x480');
mySnap=snapshot(myCam);
imshow(mySnap);
hold on
Here is a picture of the screen:
