The description of interp said, 'interp inserts zeros into the original signal and then applies a lowpass interpolating filter to the expanded sequence'. However, when i used interp to insert data into my oringal data, showing that data inserted isn't zero. Thanks!!!!!
before
after F1 = interp(F1,2)

the description says it inserts zeros AND applies the filter for interpolation. of course the filter changes the zero values.
if you want to just insert additional zeros, use the upsample function or simple dot notation like
sigUp(1:2:end)=oldSig
