在 MATLAB Online 中打开

%%This is what the tutorial says:
Screen('DrawLine', windowPtr [,color], fromH, fromV, toH, toV [,penWidth]);
%%so I did like:
[wPtr, rect] = Screen('OpenWindow', 0)
Screen('DrawLine', wPtr, [180, 40, 80], 1000, 800, 1600, 1200, [10]);
Screen('Flip', wPtr);
%%I also tried:
[wPtr, rect] = Screen('OpenWindow', 0)
Screen('DrawLine', wPtr, [180, 40, 80], 1000, 800, 1600, 1200, 10);
Screen('Flip', wPtr);

but neither of them can change the penwidth of line.. plz help me

This sounds more like a Psychtoolbox problem than a MATLAB problem.
