Read Olivetti face database
A = FACES(SUBJECTS,PHOTOS)
This creates a dataset A containing the desired photos (92*112 pixels) of the desired subjects (1 <= SUBJECTS <= 40). For each subject 10 photos are available (1 <= PHOTOS <= 10). SUBJECTS and PHOTOS may be vectors. The size of A is (LENGTH(SUBJECTS)*LENGTH(PHOTOS),92*112). The stored photos can be displayed by SHOW(A).
FACES first reads a datafile ORL and then converts it to a dataset. In case ORL is not available, it may be automatically downloaded and installed. If this fails an error is generated.
