True if A is present and false otherwise.PRODUCT 90Returns the product of the elements of the supplied array.SynopsisPRODUCT(ARRAY [,DIM] [,MASK])ArgumentsThe ARRAY argument is an array of integer, real or complex type. The optional DIM argument is avalid dimension (valid dimensions are between the values 1 and n where n is the rank of the array).The optional MASK argument is of type logical and conformable with the supplied array.
