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.
ndims - Returns the number of dimensions of the data field in a DataSet object.
