Utility functions provide services that validate or return metadata about series or matrices stored in input tables, extract results from multi-layered analytic results table (ART) table, provide plotting support, and support conversion of a table to a form that is usable as a source for another function.
| Function | Description |
|---|---|
| TD_SINFO | Returns metadata that describes a logical series. |
| TD_COPYART | Creates a copy of an existing ART. |
| TD_EXTRACT_RESULTS | Retrieves auxiliary result sets stored in an ART. |
| TD_FILTERFACTORY1D | Creates finite impulse response (FIR) filter coefficients. |
| TD_IMAGE2MATRIX | Converts JPEG or PNG images to matrixes with payload values being the pixel values. |
| TD_INPUTVALIDATOR | Validates data and finds indiscreet data that was passed to a series or matrix. |
| TD_ISFINITE | Evaluates a variable or expression to determine if it is a finite floating value. |
| TD_ISINF | Evaluates a variable or expression to determine if it is an infinite floating value. |
| TD_ISNAN | Evaluates a variable or expression to determine if it is a NaN (Not-a-Number) value. |
| TD_MINFO | Returns metadata that describes a logical matrix. |
| TD_PLOT | Provides the ability to generate on-demand plots. The generated plots can be either univariate, multivariate, or composite in nature. |
| TD_CONVERTTABLEFORUAF | Converts an input table consisting of valid data types into a table whose data layout is compatible with UAF series or matrix specifications. This function is a SQL-MR table operator. |
| TD_TRACKINGOP | Uses geospatial coordinates to track an object and compute such metrics as trip distance, speed, time, and so on. |
