ISCLASS check if class is present in the data set T=ISCLASS(A,NAME) T=ISCLASS(A,{NAME1,NAME2,...}) Check if there are only the given classes present: T=ISCLASS(A,{NAME1,NAME2,...},'only') INPUT A Data set NAME Class name (string) OUTPUT T Logical value (1 if class with NAME is present in a.lab) DESCRIPTION ISCLASS implements a quick test if a class is present in the data set labels. If a cell array of strings is given, ISCLASS returns 1 only if all names in the cell array are present in A.lab.list. ISCLASS also allows to check if the given classes are the only ones present using the extra 'only' flag. ISCLASS is a useful validation step at the beginning of a algorithm function which is assuming specific type of data sets. SEE ALSO SDALG
