It looks as though fdatool is GUI only. (I don’t use it often.) Exporting the filter it designs appears to be straightforward. See the documentation for Using FDATool for details.

There are a number of fir filter design functions that you can use in your .m-files. The firls function may come closest do doing what you want. Explore them to see which works best for you.

thank you

I found another way to export the result.

h = fdatool; hFv=fvtool(h.filter);

According to the documentation the fvtool return a figure handle but I can't save the figure using savefig. But savefig(gcf,'f.fig') works.

My pleasure.

I wasn’t quite certain what you wanted. I know fdatool can export its filter designs, but I thought you wanted to do it programmatically, not using the GUI. I’m glad you got that sorted.
