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.
