matlab - 沿屏幕移动

Question

我不太擅长 Matlab，我的实验室实验需要帮助。我需要创建一个完整尺寸的图像/gif/视频吗？（全显示器尺寸），由白色背景和一个从左向右移动的黑色小方块组成。我需要以后能够修改这个正方形的大小、位置和速度。非常感谢！

For this sort of thing, Psychtoolbox is your friend. I don't have experience with it, but it is a MATLAB toolbox perfectly designed for full screen visual stimuli.

The toolbox contains an existing example called 'moving line demo':

MovingLineDemo([xv=10][, twolines=0][, screenid=max])

Shows a pair of vertical lines, or a single line, which travel
horizontally across the display from the left to the right, repeating
infinitely.

See if you can edit this to suit your need; if you get stuck, come back to ask a more specific question!
