I'm trying to use the pca() function from the stats toolbox and I'm getting an error from within the pca function itself:
defaults = {'svd', true, true, p, 'complete',...
ones(1,n,'like',x) ,ones(1,p,'like',x), [], [], statset('pca')};
Error using statset
No default options available for the function 'pca'.
I'm not sure what the issue could be but MATLAB also says in the documentation for pca():
Options for the iterations, specified as a comma-separated pair consisting of 'Options' and a structure created by the statset function.
I tried investigating the problem but I can't find any other recorded instances of this error.

Your code is working fine when I tried to run at my end given that your values for p, x and n are correct.
Please find the documentation link for “pca” function here: https://www.mathworks.com/help/stats/pca.html?searchHighlight=pca%20function&s_tid=srchtitle_pca%20function_1#d124e743715

Ran in:
Let's make sure you're using the pca and statset functions included with Statistics and Machine Learning Toolbox rather than other functions by those names in third-party products. What do these commands show on your machine?
which -all pca
/MATLAB/toolbox/stats/stats/pca.m /MATLAB/toolbox/stats/bigdata/@tall/pca.m % tall method /MATLAB/toolbox/stats/gpu/@gpuArray/pca.m % gpuArray method
which -all statset
/MATLAB/toolbox/stats/stats/statset.m
