Hi,
Based on the naming convention mentioned in https://www.mathworks.com/help/matlab/ref/mpmcreate.html?s_tid=srchtitle_support_results_1_mpmcreate, package display name should be a string scalar.
MATLAB’s MPM packaging does not support +namespace folders (like +stdlib), you can try renaming it without a "+" sign.
Hope it helps!
Thanks
