How do I get the distance between the point and the hyperplane in MATLAB 2021a fitcsvm?

Nested cross-validation method gives me the best model 1x1 ClassificationSVM, please see attached. This models gives an accuracy of 94.53% (using crossval).
I was wondering if there is an easy way to calculate the distance between the point and the hyperplane from this output?

From my understanding you are trying to find the distance of a particular data point from the hyperplane. I can recommmend you using the the "predict" function to get the Classification Score which is the signed distance of a point x form the decision boundary and ranges from -∞ to +∞.
You can learn more about the use of "predict" function here.
Hope this helps!
