niHWS_SetScalingCoefficients
C Function Prototype
tHWS_Status niHWS_SetScalingCoefficients (tHWS_WfmRef wfmReference, long numCoeffs, const double* coeffArray);
Purpose
Establishes an nth degree polynomial scaling function.
When an analog waveform stored as integer data is retrieved by a floating-point Read or Retrieve function, NI-HWS scales the data according to this polynomial scaling function.
Parameters
| Name | Type | Description |
|---|---|---|
| wfmReference | tHWS_WfmRef | A reference to the waveform. Waveforms are identified by reference for purposes of setting and getting waveform attributes and reading and writing data. |
| numCoeffs | long | The number of coefficients in coeffArray. |
| coeffArray | const double* | The array of polynomial scaling coefficients. The coefficient for the nth term
of the polynomial is contained in the nth index of
coeffArray.
For example, the coefficients for a 2nd degree polynomial, y = ax2 + bx + c would be
coeffArray[0] = c |
