%% PCA
q=21;
% PERFORM PCA
[coeff,Data_PCA,latent,tsquared,explained,mu] = pca(Data, 'NumComponents', q); %this pca function need for run this code.
% compute and display explained variation
disp(strcat("Top ", string(q), " principal components explain ", ...
string(sum(explained(1:q))), " of variation"))
% compute independent components from principal components
Mdl = rica(Data_PCA, q); %this rica function need to run this code.
Data_ICA = transform(Mdl, Data_PCA);

The Statistics and Machine Learning Toolbox is an extra-cost product that is not included in most licenses.
Your version R2019a is new enough that if you use the Add-On Explorer to search for the toolbox, then if you are already licensed for the toolbox it will allow you to install it, and if you are not already licensed it will offer to let you purchase the toolbox. (I do not know if the purchase of such an old toolbox is still possible.)
