changing one value

Here we take a 30 component vector, and we interpolate it into a 600 component vector. Let's look at both linear and nearest interpolation.

sp = output spectrum not shaped

SP = output spectrum shaped

spec : blue = abs(SP), orange = abs(sp)

abs : blue = abs(abs(SP)-abs(sp)), orange = abs(SP-sp)

ang : blue = ang(SP)-ang(sp), orange = ang(SP-sp)

Both are shown as depending on how we measure things, we might get one or the other

changing all values

Here we fix a random input of 30 component vector, and do the same thing.
