I have a simulink block diagram that takes input from a webcam and gives it to a matlab m-file. In the m-file, I run a function to call a python program to run a few image processing techniques on the incoming real-time video. My m-file is as follows:
function final=fcn(frame)
coder.extrinsic('py.importlib.import_module');
G = py.importlib.import_module('video_3',frame);
final = coder.nullcopy(zeros(size(frame)));
final = G;
end
When I run the simulation, I get the following error:
"Conversion of MATLAB 'single' to Python is only supported for 1-N vectors."
My simulink block diagram is as follows :
Any suggestions?
