Matlab - PCA analysis and reconstruction of multi dimensional data - Stack Overflow Yes, but how do they work? I mean, which one of those are the eigenvalues and which one are the eigenvectors? And how can I perform data reconstruction based on the output of princomp function? – Simon Oct 2 '12 at 10:16
Using Matlab and Principal Component Analysis (PCA) to Reduce Dimensionality of .csv Data | James Ro This information is out of date really, I have a much easier method here that does away with doing everything yourself. I used Matlab to reduce the number of dimensions in my gesture data. After a bit of experimentation with different numbers of dimension
PCA demystified - Matlabtips.com | Learning Matlab for new and advanced users This was a very clear tutorial on PCA—thank you. In the future, it would be great if you could list some examples of how different types of studies and data are analyzed with PCA. It’s clear why the poll data works (there’s a clear set of potentially corr
