Hi,

A subroutine record calls a user defined function with a pointer to the record structure
as an arugument. It means you can get a waveform data from input link, such as prec->inpa.
However, you cannot put waveform data as .VAL field of the subroutine reocrd.
.VAL field of the subroutine record is defined as DBF_DOUBLE.


It should not be so difficult to combine a subroutine record and a wave form record
for creating new subroutine record with waveform output.


If you just needs a linear transformation of waveform data, our colleague has
a record support for such job, by the way.
We also have a concat record which concatenate several waveform (or scaler) data into
a single waveform data.


regards,

Noboru

hi, all
Has anyone implemented array processing with a
subroutine record?
I want to access the values in a waveform (WFM) record with a
subroutine record, cacultate for each element and pass the array to the output. +-------+ WFM -->|a out|----> WFM | | ai -->|b | | | ai -->|c | for idx=0..499
| | (a[idx] - b ) * c
| SUB- | | ROUT- |
| INE |
