Hi I am trying to display the results of my PCA analysis on a biplot by following the example on https://www.mathworks.com/help/stats/biplot.html . I want to add the labels to the lines and scores. After I created hid to label my houses on the graph I get the following error message:
VarLabels' value must be a string array, a character array, or a cell array of character vectors with one ↑
Error: Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or
other syntax error. To construct matrices, use brackets instead of parentheses.

Is there source that I can refer to to fix this issue and also add the labels on the scores display as dots? Thanks in advance for your help
biplot(coefs(:,1:2)),'Score',score(:,1:2); %% graph step
hid = {'House1','House2','House3','House4','House5','House6','House7','House8' 'House9'}; % Array of variable labels for lines on the graphs
h = biplot(coefs(:,1:2),'Scores',score(:,1:2),... 'Color', 'b', 'Marker', 'o', 'VarLabels', hid);
