nice written routine (short and clear) but:
some optimisation could be done (find is done twice, while not necessary);
not working correctly if extreme points have successive equal points. example:
[x1,y1,x2,y2]=envelope(1:10,[0 1 -1 2 2 -2 -2 1 -1 0])

The simpler the better.. Just great!!!!

[Koustuv Debnath]

Quite good.
Did a lot of serch but no other m file was online.

[Monica Voinescu]

Exactly what I needed. Short and efficient.

great

[patrick huber]

perfect, recursive envelopes works great

[Daniel Morim]

It isn't work well for "any signal".

[SASSOLAS Benoît]

There is some problems when signal contains some noise.

good

[Jveer T]

3d data as well?

[jp beat]

try and test

[Alonso Tapia]

looks like it works fine only for Matlab/Simulink generated data

[Alonso Tapia]

i couldn´t edit, so i will add another commentary..
any given data without noise should be the description
