In practice, materials science information must be evaluated and compared in a statistical manner. Traditional materials science practice involves pre-processing steps that identify material features; from there statistics of the features are extracted. Examples of feature statistics are orientition distribution functions, volume fraction, variance; the statistics are feature identifiers in materials science.
Spatial statistics provide a powerful objective statistical quantifier for materials science information. Spatial statistics have effective statistical measures embedded in them such as volume fraction and specific surface area.

I suggest using Mark Tygert's randomized Principal Component Analysis function that can be downloaded from http://cims.nyu.edu/~tygert/pca.m .
