<P><FONT SIZE=2>Hello.<BR>
I am using the module i.pca and i would like to understand how it works. I have browsed the code but i still have some questions:<BR>
<BR>
- does it subtract the mean before computing the covariance matrix?<BR>
- what does "transposing the matrix" mean?<BR>
- what is the final step before defining writing the output? i read somewhere that it involves multiplying elements but i am not sure which are they.<BR>
<BR>
I wanted to expand my knowledge so any feedback would be great.<BR>
