niHWS Get Scaling Coefficients
Retrieves the coefficients of an nth degree polynomial scaling function.
When an analog waveform stored as integer data is retrieved by a floating-point Read or Retrieve VI, the data is scaled according to this polynomial scaling function.
|
waveform reference in is a reference to the waveform. Waveforms are identified by reference for purposes of setting and getting waveform attributes and reading and writing data. | ||||||
|
error in (no error) can accept error information wired from VIs previously called. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs.
The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

|
waveform reference out is the copy of waveform reference in you use for input into the next NI-HWS VI in your program. | ||||||
|
actual number of coefficients is the actual number of coefficients returned in coefficient array. | ||||||
|
coefficient array is the array of polynomial scaling coefficients. The coefficient for the nth term of the polynomial is returned in the nth index of the coefficient array.
For example, the coefficients for a 2nd-degree polynomial: y = ax2 + bx + c would be coefficient array[0] = c |

|
error out passes error or warning information out of a VI to be used by other VIs.
The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.
