i want draw a plot

handles.axex5 graph * handles.axex3 graph = handles.axes4

What can I do T,T?

I have no idea....

[Geoff Hayes]

Are you saying that you want to multiply the output in axes3 with that from axes5 and draw that on axes4? What is axes4 supposed to represent?

[rollcakes]

PF(in function mycallback(gcf, event_data, handles, filter_num) *Xfs(in function list_callback(gcf, event_data, handles) = axes4

but i don't know plot(f,Xfs*PF)

[Geoff Hayes]

But what does PF and Xfs represent? The former is (or can be?) a 1x64 array whereas the latter can be a 1x3142 result of a FFT shift. Please clarify why you are trying to multiply these two arrays.

[rollcakes]

i wnat make filter... TT how I can change two arrays to same

[rollcakes]

Sorry thanks...
