colnames

Syntax

ReturnColNames = colnames(DMObj) ReturnColNames = colnames(DMObj, ColIndices) DMObjNew = colnames(DMObj, ColIndices, ColNames)

Input Arguments

`DMObj`	DataMatrix object, such as created by `DataMatrix` (object constructor).
`ColIndices`	One or more columns in `DMObj`, specified by any of the following: Positive integer Vector of positive integers Character vector specifying a column name Cell array of character vectors Logical vector
`ColNames`	Column names specified by any of the following: Numeric vector Cell array of character vectors Character array Single character vector, which is used as a prefix for column names, with column numbers appended to the prefix Logical `true` or `false` (default). If `true`, unique column names are assigned using the format `col1`, `col2`, `col3`, etc. If `false`, no column names are assigned. Note The number of elements in `ColNames` must equal the number of elements in `ColIndices`.

Output Arguments

`ReturnColNames`	Character vector or cell array of character vectors containing column names in `DMObj`.
`DMObjNew`	DataMatrix object created with names specified by `ColIndices` and `ColNames`.

Description

ReturnColNames = colnames(DMObj) returns ReturnColNames, a cell array of character vectors specifying the column names in DMObj, a DataMatrix object.

ReturnColNames = colnames(DMObj, ColIndices) returns the column names specified by ColIndices. ColIndices can be a positive integer, vector of positive integers, character vector specifying a column name, cell array of character vectors, or a logical vector.

DMObjNew = colnames(DMObj, ColIndices, ColNames) returns DMObjNew, a DataMatrix object with columns specified by ColIndices set to the names specified by ColNames. The number of elements in ColIndices must equal the number of elements in ColNames.
