Reset the object size of a dataset
A = SETOBJSIZE(A,OBJSIZE)
By default, the object size of a dataset A is given by the number of objects, i.e. the number of rows in the DATA field of A. If the objects 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 OBJSIZE. The product of all elements in OBJSIZE has to be equal to the number of rows in the DATA field of A.
