I'd like to add string data column and row labels (aka "headers") to a 5x13 matrix. I've expanded the matrix to 6x14 with NaNs to accommodate these labels on both the x and y.

I've tried the below threads' approaches, and I'm apparently missing something in each case, and am unable to modify to get them to work for me: https://www.mathworks.com/matlabcentral/newsreader/view_thread/245987 https://www.mathworks.com/matlabcentral/answers/89195-how-to-put-heading-for-columns-of-matrix

I'm really trying to stay out of the Excel world. Truly, I am... but this one is making that temptation hard to resist.

Thank you, everyone.

Why don't you use table instead?

sample = rand(3,3);
rowNames = {'a','b','c'};
colNames = {'x','y','z'};
sTable = array2table(sample,'RowNames',rowNames,'VariableNames',colNames)

sample=rand(20,100);
rowNames="row_"+ (1:20)'; % Doubles get converted to strings when they are concatenated with them
colNames="col_"+ (1:100);
sTable = array2table(sample,'RowNames',rowNames,'VariableNames',colNames);
