[GRASS-dev] reg i.pca module

[Rashad M]

Hi All,

i.pca outputs raster bands and the pixel values are transformed obivously.
But anyone can tell me how the transformation works

if a pixel P1 has value X after i.pca it will be Y

Is there any specific math equation that is applied to every pixel by PCA?
