Dataset Array Operations

This table lists available methods for dataset arrays. Many of the methods are invoked by familiar MATLAB operators and do not need to be called directly. For full descriptions of individual methods, type

help dataset/methodname
Dataset MethodDescription
catConcatenate dataset arrays. The horzcat and vertcat methods implement special cases.
datasetCreate dataset array.
datasetfunApply function to each variable of dataset array.
dispDisplay dataset array, without printing data set name.
displayDisplay dataset array, printing data set name. This method is invoked when the name of a dataset array is entered at the command prompt.
doubleConvert dataset variables to double array.
endLast index in indexing expression for dataset array.
getGet dataset array property.
horzcatHorizontal concatenation for dataset arrays (add variables). This method is invoked by square brackets.
isemptyTrue for empty dataset array.
joinMerge observations from two dataset arrays.
lengthLength of dataset array.
ndimsNumber of dimensions of dataset array.
numelNumber of elements in dataset array.
replacedataConvert array to dataset variables.
setSet dataset array property value.
singleConvert dataset variables to single array.
sizeSize of dataset array.
sortrowsSort rows of dataset array.
subsasgnSubscripted assignment for dataset array. This method is invoked by the parenthesis, dot, and curly brace indexing.
subsrefSubscripted reference for dataset array. This method is invoked by the parenthesis, dot, and curly brace indexing.
summaryPrint summary statistics for dataset array.
uniqueUnique observations in dataset.
vertcatVertical concatenation for dataset arrays (add observations). This method is invoked by square brackets.
