Extending HCL OneDB™Beyond standard relational database objects, HCL OneDB™ can be extended to handle specialized data types, access methods, routines, and other objects. HCL OneDB™ includes many built-in extensions that are fully integrated in the database server. HCL OneDB™ also provides DataBlade® modules, which are packages of extended database objects for a particular purpose and that are installed separately from the database server. Alternatively, you can create your own user-defined objects for HCL OneDB™.

TSCompute_NonConstraint_Dist functionThe TSCompute_NonConstraint_Dist function calculates the DTW distance between two time series sequences without constrainsts.

TSCompute_NonConstraint_Dist function

The TSCompute_NonConstraint_Dist function calculates the DTW distance between two time series sequences without constrainsts.

Syntax

TSCompute_NonConstraint_Dist (
                 sequence1     list,
                 sequence2     list) 
RETURNS DOUBLE PRECISION

sequence1: A list of values that is returned by the ValueAsCollection or TSGetValueList function.
sequence2: A list of values that is returned by the ValueAsCollection or TSGetValueList function.

Usage

Run the TSCompute_NonConstraint_Dist function to calculate the distance between two time series sequences without constraints. The length of the sequences must be the same. See Dynamic time warping.

Returns

A number that represents the distance between two sequences.
