Utility functions provide services that validate or return metadata about series or matrixes stored in input tables, extract results from multilayered 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.
Functions:
- TD_SINFO
- Returns metadata that describes a logical series.
- TD_MINFO
- Returns metadata that describes a logical matrix.
- TD_INPUTVALIDATOR
- Validates data and finds indiscrete data that was passed to a series or matrix.
- TD_EXTRACT_RESULTS
- Retrieves auxiliary result sets, such as the secondary and tertiary layers, stored in an analytic result table (ART).
- TD_PLOT
- Provides the ability to generate on-demand plots. The generated plots can be univariate, multivariate, or composite.
- 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.
- TD_TRACKINGOP
- Calculates geospatial data for trip distance, speed, time, and so on.
- TD_COPYART
- Creates copy of existing analytics result table (ART).
- TD_FILTERFACTORY1D
- Creates finite impulse response (FIR) filter coefficients based on certain parameters and stores the filters in a common table for reuse.
- TD_IMAGE2MATRIX
- Converts JPEG or PNG images to matrixes with payload values being the pixel values.
- TD_ISFINITE
- Determines if variable or expression is a finite floating value. A finite floating value is not a NaN (Not a Number) value and is not an infinity value.
- TD_ISINF
- Determines if floating-point argument of variable or expression is infinite number. Determines if a database table contains positive or negative infinite values.
- TD_ISNAN
- Determines if floating-point argument of variable or expression is a NaN (Not-a-Number) value.
- TD_MATRIX2IMAGE
- Converts matrix to image.
