Anybody here help with this?
I tried using conv and deconv to try something, but it does
not render the expected solution.
If I use:
>> stept=zeros(1,501);stept(1:251)=1;
then smooth it with a guassian shaped curve
>> smoothedstept=conv(sept,guassiancurve);
now recover the step by trying to deconvolve doesn't work
>> out=deconv(smoothedstept,guassiancurve);
produces an error that the first term is supposed to be
non-zero.
If I do this convolution followed by deconvolution with
truncated waveforms, it seems to work
so how do I fix it to work?
