nanmin — Compute minima while ignoring NaN values.
nanmin(A, ...) is a compatibility alias for min(A, ..., 'omitnan') and supports the legacy pairwise nanmin(A, B) form.
Syntax
B = nanmean(A, ...)Inputs
| Name | Type | Required | Default | Description |
|---|---|---|---|---|
A | Any | Yes | — | Input value. |
args | Any | Variadic | — | Method, dimension, or option arguments. |
Returns
| Name | Type | Description |
|---|---|---|
B | Any | Result value. |
Errors
| Identifier | When | Message |
|---|---|---|
RunMat:missing:InvalidArgument | Arguments do not match a supported missing-value syntax. | missing-value builtin: invalid argument |
RunMat:missing:UnsupportedType | The input type has no missing-value representation in RunMat. | missing-value builtin: unsupported input type |
RunMat:missing:InternalError | Internal shape or table materialization fails. | missing-value builtin: internal error |
How nanmin works
- Dimension and
"all"options supported byminare forwarded. nanmin(A, B)returns pairwise minima, ignoring NaN from either side when the other side is present.
Examples
Ignore NaN values
m = nanmin([NaN 2 3])Expected output:
m = 2Pairwise minima
B = nanmin([NaN 4 3], [2 NaN 5])Expected output:
B = [2 4 3]Using nanmin with coding agents
Open a RunMat example with live inputs, then ask the agent to explain how nanmin changes the result.
Run a small nanmin example, explain the result, then change one input and compare the output.
