Purpose
Performs a transpose (rows become columns and columns become rows) on a two-way DataSet object.
Synopsis
- x = x'
- x = transpose(x)
Description
Returns the transposed DataSet object x in which rows are now columns and vice versa (mode 1 becomes mode 2 and mode 2 becomes mode 1). All fields are transposed as necessary. This specific command only operates on vector and two-way DataSet objects. To modify multi-way DataSet objects (more than 2 modes), use the PERMUTE method.
Example
The following demonstrates the transpose of a DataSet object, a:
>> a.data
ans =
1 2
30 40
>> a=a';
>> a.data
ans =
1 30
2 40
