In addition to the specific methods listed below, a number of standard MATLAB functions are overloaded for [[DataSet_Object|DataSet objects]] but otherwise work as documented for standard data types. The following methods operate on the underlying data field of a DataSet object only and have no effect on any other fields:

In addition to the specific methods listed below, a number of standard MATLAB functions are overloaded for DataSet objects but otherwise work as documented for standard data types. The following methods operate on the underlying data field of a DataSet object only and have no effect on any other fields:

minus (-)
plus (+)
times (.*)
rdivide (./)
ldivide (.\)
double
single

To get help on any DataSet object method, use the command: help dataset/method where method is the name of the method for which you want help.
