Exporting a Filter Design

You can save your filter design by

Exporting Coefficients or Objects to the Workspace

You can save the filter as filter coefficients variables or as a dfilt or qfilt filter object variable. To save the filter to the MATLAB workspace:

  1. Select Export from the File menu. The Export dialog box appears.
  2. Select Workspace from the Export To menu.
  3. Select Coefficients from the Export As menu to save the filter coefficients or select Objects to save the filter in a filter object.
  4. For coefficients, assign variable names using the Numerator and Denominator text boxes in the Variable Names region. For objects, assign the variable name in the Discrete or Quantized filter text box. If you have variables with the same names in your workspace and you want to overwrite them, select the Overwrite Variables box.
  5. Click the OK button.
