comment How would it looks the Fourier series of this signal?
Let us continue this discussion in chat.

comment How would it looks the Fourier series of this signal?
You can see in the picture: part of sine + part of square + part of triangle + part of inclinated straightline... and so on. i.e. random/crazy signal.

No. That's a "hypothetical" signal I'd like to get summing up sin.I have nothing, and I need some "random" fourier series that can give to me such a signals.

but I don't have g(t). I need to create it summing sin (so, the inverse process).

comment How to choose new points after grouping/resampling?
think of this also in this way: If I just choose blu point every fifth samples Ill lost an important information: the max and min peaks at every slope. I mean: if the curve change the inclination (check the first slope) it will take a blu point that could be inferior to the actual peak. thus, min/max absolute values for the signal will change. I don't want this...

comment How to choose new points after grouping/resampling?
yes you are right. but I don't have that kind of control in what I'm doing. I have some primitives that does this finding min and max peaks (which can help to draw a waveform, for example). This is what I have unfortunately...

Real signal got something like 700000 points, which I cant display on a limited amount of pixel. So Im resampling...

exactly that! It is far away from where it should stay (blu One). do you see?

Not really! See the 4° slope: the 3° choosed point is wrong...

I don't need to recostruct blue value. I'm starting from blu, reducing points. Once reduced, I need to draw the simil-signal that would be if I kept blu values. Do you see? It's a sort of "compressing" values...

comment How to scale/stretch this signal?
Uhm, it seems to works! What was wrong with my function?

@EricTowers: I've added the whole signal, so you can check it out.

comment Round to down - Remainder emulation?
I could use round(x-1/2). But for int (i.e. tie breaking 0.5) it round ho even (which I don't want; it is not flooring). What do you mean with x-i for integers 1..2? I don't get it...

comment How can I bend a straight line?
Nice. With some math and programming, I got Cubic Bézier curves and makes my own bend! Thanks a lot!

comment Can I do this kind of process with a pure math function?
As I said, I can't do any assignement, and prev = n is!

No, can't use boolean logic. This is what I can use: image-line.com/support/FLHelp/html/plugins/…

Can't use this "syntax". I have to write it as "command line/math expression" in a software. Such as y= Input*0.25 + 0.25...

Sorry, I've updated the question ;)
