 MATLAB® interface to [OpenTelemetry™](https://opentelemetry.io/), based on the [OpenTelemetry Specification](https://opentelemetry.io/docs/specs/otel/). OpenTelemetry is an observability framework for creating and managing telemetry data, such as traces, metrics, and logs. This data can then be sent to an observability back-end for monitoring, alerts, and analysis.
