psychtoolbox突然无法运行

前两天打开psychtoolbox发现之前写好的实验无法正常运行，运行时一直显示灰屏，没有倒三角警告和圆点动画，运行DotDemo的时候只有psychtoolbox和圆点动画，没有倒三角警告。试过重装ptb但还是不行，有人知道什么原因吗？

Approximate translation:

Two days ago, I opened psychtoolbox and found that the experiment I wrote before could not run normally. When running, it always displayed a gray screen without an inverted triangle warning and dot animation. When running DotDemo, there was only psychtoolbox and dot animation, but no inverted triangle warning. I tried reinstalling ptb but it still doesn't work. Does anyone know the reason?

Hi,

I found following answer in the community regarding "psychtoolbox". It seems it is a third party toolbox.

"Please note that the MEX file belongs to Psychtoolbox which is a third-party toolbox not owned by MathWorks. Therefore, it is not an officially supported MATLAB function."
