Hello,

I'm trying to do a linear interpolation of vector y.

So where the 0 begins, I want to take the previous value that is 1 and where the 0 end, the next value that is 4 and interpolate.

That for the next section too, From 3 to 2

Can anyone help please

yn = interp1( idx_start,idx_end ,'spline');

y = [1 2 1 0 0 4 2 1 2 3 0 0 0 2 4 2 2 1]

for k = 1:length(y)-1

if y(k)== 0

idx_start = y(k-1)

break

else

while y(k)== 0

k = k+1

if k>0

idx_end = y(k)

break

end

end

end

end
