Exporting a Filter Design

You can save your filter design by:

• Exporting the filter coefficients to the MATLAB workspace
• Exporting the filter coefficients to a text file
• Exporting the filter coefficients to a MAT-file

To save your filter coefficients to a file or the workspace, select Export under the File menu.

Let's export the filter coefficients to the workspace.

Exporting Filter Coefficients to the Workspace

To save filter coefficients as variables in the MATLAB workspace:

• Select Export from the File menu. The Export dialog box appears.
• Select Workspace from the Export To menu.
• Assign variable names using the text boxes in the Variable Names region.
• Press the OK button.

Exporting Filter Coefficients to a Text File

To save filter coefficients to a text file:

• Select Export from the File menu. The Export dialog box appears.
• Select Text-file from the Export To menu.
• Press the OK button. The Export Filter Coefficients to a Text-file dialog box appears.
• Choose a filename and press Save.

The coefficients are saved in the text file that you specified, and the MATLAB Editor opens to display the file.
