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.
Methods Defined or Overloaded for DataSet Objects
- anyexcluded - Reports if any element is excluded in a DSO.
- cat - Generic concatenation of DataSet objects.
- delsamps - Deletes or excludes the specified samples, rows, or other dimension from a DataSet object.
- disp - Display summary of DataSet object contents.
- explode - Extract all variables from a DataSet object.
- findset - Locate a set within a label field (axisscale,label,class) in a DataSet.
- get - Get field/property values from a DataSet object.
- horzcat - Horizontal concatenation of DataSet objects.
- isempty - Returns Boolean true if the DataSet object data field is empty.
- length - Returns the length of the data field in a DataSet object.
- listsets - For a given field and mode list the sets available.
