Problem using binScatterPlot plotting scores of PCA
显示 更早的评论
I am trying to follow the webinar Predictive Maintenance with MATLAB: A Prognostics Case Study but having problem using binScatterPlot. It's giving me the error "Undefined function 'binScatterPlot' for input arguments of type 'double'."
What is basically the source of the problem and how can I fix it? the code is something like this-
[coeff, score, latent] = pca(XtrainStandard);
binScatterPlot(score(:,1),score(:,2),[50,50],'Gamma',0.01)
Thank you

As the document of binScatterPlot says, input of binScatterPlot should be tall arrays. I think your XtrainStandard is not a tall array, so, you need to convert tall arrays.
[coeff, score, latent] = pca(tall(XtrainStandard));
binScatterPlot(score(:,1),score(:,2),[50,50],'Gamma',0.01)
