Saving Magnitude Response from FDATool

Hello,

I'd like to save the magnitude response that is created from the FDATool as a .fig file and then export the data use to generate the .fig file into Excel, so that I can plot the magnitude response of the filter in Excel.

Any help would be much appreciated, I can only find ways to export the figure as an image.

Kind Regards

Edward

Hello,

After a little bit of digging, I managed to find a solution as follows:

1. Load the Filter Design and Analysis tool by typing fdatool into the command window
2. Design your filter
3. Click 'Full View Analysis' (White Square Icon)
4. Click 'Edit Plot' (Mouse Pointer Icon)
5. Click on the dataset you would like to capture
6. Return to the command window and enter:

x=get(gco,'xdata').';
y=get(gco,'ydata').';

The values used to plot the magnitude response in the FDATool are now stored in two vectors, x and y, these were transposed into columns to make them more manageable. Then simply open the vectors from the workspace, hit 'Ctrl + A' to select all and paste into Excel, or export the data as required: https://uk.mathworks.com/help/stats/export-dataset-arrays.html
