ProfileDistance
Computes the [mean] square error between two profiles.
| Name | Type | Description | |
|---|---|---|---|
 |
inProfile1 | Profile | First input profile |
|
inProfile2 | Profile | Second input profile |
|
inDistanceMeasure | DistanceMeasure | Measure of distance |
 |
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.
Errors
