upsampling and interpolation

Postby Shark86 » Sun Jun 10, 2012 4:22 pm

Hello Everybode,

I have a problem in signal processing using MATLAB.
I can see that both commands 'interp' and 'upsample' commit the same operation: "increase sampling rate by integer factor".
Still, they do NOT give the same result.

I wish to ask what is the difference between these command? I looked up at the MATLAB help, and I couldn't understand what it is.
