To read the values in the COMSOL model in real-time and output them in real-time after calculation in MATLAB, the “ mphinterp ” function can be used. However, the issue with the given function is that the value of x is always set to 0, so the output of this function will always be 0.

The P-value is used as an alternative to the rejection point to provide the least significance at which the null hypothesis would be rejected.
Webb26 apr. 2024 · The p-value is the probability under the null hypothesis of us observing a test statistic at least as extreme as the one we actually saw. The lower this probability, the more extreme our observed data is. And the more extreme the data is if the null was true, the more evidence there is that the null isn’t true.
WebbThe p-value of a test is the probability of observing a test statistic at least as extreme as the one computed given that the null hypothese is true True 14.
