Supported Data Transformations
The following table shows the different ways you can transform data from one data domain to another. If the transformation is supported for a given row and column combination in the table, the command used by the software is listed in the cell at their intersection.
Original Data Format | To Time-Domain Data ( iddata object) | To Frequency-Domain Data ( iddata object) | To Frequency-Response Data ( idfrd object) |
---|---|---|---|
Time-Domain Data ( iddata object) | N/A | Use fft | |
Frequency-Domain Data ( iddata object) | Use ifft (works only
for evenly spaced frequency-domain data). | N/A | |
Frequency-Response Data ( idfrd object) | Not supported | Use iddata . The software
creates a frequency-domain iddata object that
has the same ratio between output and input as the original idfrd object
frequency-response data. |
|
Transforming from time-domain or frequency-domain data to frequency-response data is equivalent to creating a frequency-response model from the data. For more information, see Frequency-Response Models.
