filloutliers — Fill outliers in numeric arrays.
filloutliers detects outliers in supported dense real arrays and replaces them using a requested fill method. Documented single and double inputs preserve their class. Typed-integer input is a mode-gated RunMat extension with a deliberate double statistics/result boundary. Integer arrays are admitted only when their exact value span is at most 2^53; wider spans are rejected instead of collapsing distinct observations.
Syntax
B = filloutliers(A, fillmethod)
B = filloutliers(A, fillmethod, findmethod)
B = filloutliers(A, ___, dim)
[B, TF] = filloutliers(___)
[B, TF, L, U, C] = filloutliers(___)Inputs
| Name | Type | Required | Default | Description |
|---|---|---|---|---|
A | Any | Yes | — | Input numeric array. |
fillmethod | Any | Yes | — | Replacement method or constant value. |
options | Any | Variadic | — | Detection method, dimension, and name-value options. |
Returns
| Name | Type | Description |
|---|---|---|
B | NumericArray | Array with outliers filled. |
TF | LogicalArray | Logical mask of detected outliers. |
L | NumericArray | Lower threshold. |
U | NumericArray | Upper threshold. |
C | NumericArray | Center value used by the detection method. |
Returned values from filloutliers depend on how many outputs the caller requests.
Errors
| Identifier | When | Message |
|---|---|---|
RunMat:outliers:InvalidArgument | Inputs, methods, dimensions, or name-value options are malformed. | outlier builtin: invalid argument |
RunMat:outliers:Unsupported | A table/timetable or advanced smoothing/interpolation form is requested. | outlier builtin: unsupported form |
RunMat:outliers:Internal | Internal tensor or logical array materialization fails. | outlier builtin: internal error |
RunMat:outliers:TooManyOutputs | More outputs are requested than the builtin can return. | outlier builtin: too many outputs |
Examples
Linearly fill an outlier
B = filloutliers([1;2;100;4;5],"linear")Fill outliers with a constant
B = filloutliers(A,0)Using filloutliers with coding agents
Open a RunMat example with live inputs, then ask the agent to explain how filloutliers changes the result.
Run a small filloutliers example, explain the result, then change one input and compare the output.
