Arguments

`DMObj1`	DataMatrix object, such as created by `DataMatrix` (object constructor).
`Row`	One or more rows in `DMObj1` by which to sort the columns. Choices are: Positive integer Vector of positive integers String specifying a row name Cell array of strings specifying multiple row names Logical vector
`'ColName'`	String that specifies to sort the columns by the column names.
`Mode`	String specifying the order by which to sort the columns. Choices are `'ascend'` (default) or `'descend'`.

Return Values

`DMObjNew`	DataMatrix object created from sorting the columns of another DataMatrix object.
`Indices`	Index vector that links `DMObj1` to `DMObjNew`. In other words, `DMObjNew = DMObj1(:,idx)`.

Description

DMObjNew = sortcols(DMObj1) sorts the columns in DMObj1 in ascending order based on the elements in the first row. For any columns that have equal elements in a row, sorting is based on the row immediately below.

DMObjNew = sortcols(DMObj1, Row) sorts the columns in DMObj1 in ascending order based on the elements in the specified row. Any columns that have equal elements in the specified row are sorted based on the elements in the next specified row.

DMObjNew = sortcols(DMObj1, 'ColName') sorts the columns in DMObj1 in ascending order according to the column names.

DMObjNew = sortcols(DMObj1, ..., Mode) specifies the order of the sort. Mode can be 'ascend' (default) or 'descend'.

[DMObjNew, Indices] = sortcols(DMObj1, ...) returns Indices, an index vector that links DMObj1 to DMObjNew. In other words, DMObjNew = DMObj1(:,idx).
