Fixed mapping, (re)set the feature size of a dataset
A = SETFEATSIZE(A,FEATSIZE)
By default the feature size of a dataset is its number of features, i.e. the number of columns in the DATA field of A. If the features are samples of a multi-dimensional data item, e.g. the pixels of an image, the original size of this data item may be stored in FEATSIZE. The product of all elements in FEATSIZE has to be equal to the number of columns in the DATA field of A.
This routine is particulary useful as A = A*SETFEATSIZE to remove image size settings for the feature size.
There is a low level version of this routine with the same name in the PRDATASET directory.
