comment Matrix form of complex numbers
I am also interested in how to adapt it for dual numbers.

Thanks! But why it returns for {{0,-1,1,0}} and {{0,1,-1,0}} the same result? It should be i and -i.

@Algohi it only changes appearance, it does not change the matrix.

@Algohi how to transform a matrix to this form? You show how to produce a matrix given a complex number, I am looking for the opposite.

If you are involved the fixing this bug, please consider employing more general methods of Fourier transform, so to get sinh(x) here, because the whole expression should return integral of the function to which it is applied. (and in general, the function's derivative of the order of the power of $(-i w)$. In this case it is -1: $ (-i w)^{-1}= i w^{-1}$, the $i$ is moved to the front of the expression. If you insert normal cosine instead, it will return sine.

@Ymareth Win7 Now it says"Cannot open C:\Program Files\Wolfram Research\Mathematica\10.0\SystemFiles\Kernel\SystemResources\Windows-x86-64\Spec‌​ialSimplifiers\Gamma.mx" And indeed... there is no such file...

@Yi Wang I also started to get answers like the following: DeveloperGammaSimplify[-1]^(-1 + x) (C DeveloperGammaSimplify[-1] + x Developer`GammaSimplify[0]) Exitting the kernel does not help.

@QuantumDot yes, my bad, but still the question about internal functions remains...
