A free program that will do all that and more is PhotoRec:

http://www.cgsecurity.org/wiki/PhotoRec

"PhotoRec is file data recovery software designed to recover lost files
including video, documents and archives from hard disks, CD-ROMs, and
lost pictures (thus the Photo Recovery name) from digital camera memory.
PhotoRec ignores the file system and goes after the underlying data, so
it will still work even if your media's file system has been severely
damaged or reformatted.

PhotoRec is free - this open source multi-platform application is
distributed under GNU General Public License. PhotoRec is a companion
program to TestDisk, an app for recovering lost partitions on a wide
variety of file systems and making non-bootable disks bootable again.
You can download them from this link."

I've used TestDisk, also written by Chistophe Grenier, with excellent
results.

Taking the first derivative of a function after taking the Fourier
transform is easy:  Just multiply each amplitude by it's frequency.

Supposing the order of the derivative is 1/2?

How would that derivative be taken in the frequency domain?

Going to make me do all the heavy lifting, are you?

Proof:

1st derivative:

multiplying each amplitude by its frequency

2nd derivative:

multiplying each amplitude by its frequency^2

Since there shouldn't be anything quirky going on:

3/2 derivative:

multiplying each amplitude by its frequency^(3/2)

So just raise each frequency to the order of the fractional
derivative.

Incredibly easy!

A Stanford youtube math prof said that people think in the time domain
but nature operates in the frequency domain.

You can really see it here.

Good afternoon,

For partial derivation (d/dx)^a o x^n
We just have to use gamma fonction.
For a=1 (d/dx)^1 o x^n = n!/(n-1)!x^(n-1)
general case, a , r real:
(d/dx)^a o x^r Gamma(r+1)/Gamma(r-a+1)*x^(r-a)
try
(d/dx)^a and (d/dx)^(1-a) upon x^n , n integer ...

This is the launchpoint for the book _Calculus in a New Key_
by D. L. Orth. It sure SOUNDS interesting, but the noninteger
derivative doesn't simplify anything I've ever worked on.

It's good to check your work.

If you want to do it with the Excel Fourier transform tool:

1. get the new phase angle from the derivative order, nu

2. get the real and imaginary parts from the new phase angle and the
absolute value of the transform and the sign of the original real and
imaginary parts.

3. multiply the phase adjusted real and imaginary by the frequency^nu

4. complex

5. inverse transform.

Bonjour,

I do not know the purpose and use of 'your' fractional
derivative.
to sum up (d/dy)^r o exp(ay) = a^r*exp(ay)
(d/dy)^r o y^n = Gamma(n+1)/Gamma(n-r+1)*y^(n-r)
We may also directly build a function g(x,y) such as
g(x+r,y) = d/dy)^r o g(x,y)
Example g(x,y) = d/dy)^x o (exp(2y)+exp(3y)
g(x,y) = 2^x*exp(2y)+3^x*exp(3y) ,

If a function cannot be represented analytically, a spreadsheet is a
convenient way to quickly look at a lot of different fractional
derivatives.

I'm still having some divide by zero issues. Excel can sometimes be
tricked into working just by using very small numbers for zero.

Instead of running low-voltage wiring, consider the
use of a cable or other control linkage. Something
like a bicycle brake cable might be easier to
connect to a power tool than a low-voltage cable is.

Lucas' reputation was built on experiences with low end British cars
and other products at a low price point. Because the Lucas electric
products, themselves, were built to a price point, they were of low
quality. If you buy cheap, you get cheap.

However, I was stunned to find that the fan motors on my 308, of
exceptional build quality (with prices that ran into 4 figures), were
also built by Lucas.

And Lucas is one of the primary electric suppliers to the Space Program.

They clearly can do it.

It's just that so few care to pay for it.

Whoever 'split' that misfortunate LED most likely applied AC mains
voltage to the leads . Seen it before . Even WITH a 1K resistor .
