Is there a built-in GUI for PCA (Principal Componente Analysis)?

Hello everyone,

I'm almost certain that I've used a built-in GUI in Matlab for PCA. However, I'm not finding it anywhere (I'm using 2015a version).

I remember that after the data input, we could choose which components to plot.

Please help! This is driving me crazy :D

Maybe in the PLS toolbox?

There is a PCA option in the "Classification Learner" App.

Hm...I can't find it. These are my installed toolboxes:

Curve Fitting Toolbox Version 3.5.1 (R2015a)

Neural Network Toolbox Version 8.3 (R2015a)

Signal Processing Toolbox Version 7.0 (R2015a)

Statistics and Machine Learning Toolbox Version 10.0 (R2015a)

Symbolic Math Toolbox Version 6.2 (R2015a)

System Identification Toolbox Version 9.2 (R2015a)

Wavelet Toolbox Version 4.14.1 (R2015a)

Sorry, I misread the documentation. The PCA GUI was only added in 2015b. Not sure what GUI you had been using before. They have examples for visualization of feature selection etc. in the documentation... not quite what you were hoping for, but maybe this helps:

Thanks.

I guess I'll have to keep looking for it anyway :P

There are some specialized PCA tools, e.g. a tool for wavelets:

Wavelet PCA

Type "wavemenu".
