ProfileDistance


Module: FoundationPro

Computes the [mean] square error between two profiles.

Name Type Description
Input value inProfile1 Profile First input profile
Input value inProfile2 Profile Second input profile
Input value inRange Range*
Input value inDistanceMeasure DistanceMeasure Measure of distance
Output value outDistance Real Output distance value

Description

The operation computes the approximate difference between two profiles using the selected distance measure.

  • If the inDistanceMeasure is set to MeanError then the resulting outDistance is the average difference between corresponding values of the profiles.
  • If the inDistanceMeasure is set to MeanSquaredError then the resulting outDistance is the average squared difference between corresponding values of the profiles.

The operation requires that the profiles being compared have equal sizes, otherwise an error with appropriate description occurs.

Examples

Mean Squared Error between the sample profiles equals 25245.070.

Mean Error between the sample profiles equals 0.803.
