Retagging release from 4.0.0-rc4 to 4.0.0.

Fixed on the stable branch. The fix for this regression will be included in a 4.0.1 bug fix release.

Michael: it does work, but the return value is not quite the same result. Specifying the dim argument indicates that the input will be shifted only along that dimension. The default is to shift along all dimensions.

As a workaround,

appears to work.
Mike: Is this correct?

Confirmed, thanks for reporting! I think the 4.0 release process has already begun, this is an easy fix but will have to wait until a future 4.0.1 bugfix release. This is due to the redefinition of the ismatrix function in the 4.0 release.

For the other devs: I have a local fix for this already, just holding off pushing to stable because I know jwe has already started making the release but I don't see the 4.0.0 release tag on the stable branch yet so I don't want to mess that up.

Just to clarify, fftshift seems to allow only 1D and 2D arrays now. MATLAB and Octave3.8 accept any no. of dims.

I just compiled 4rc4 using the MXE package. I'm seeing this error with fftshift:


error: fftshift: expecting vector or matrix argument
error: called from
    fftshift at line 80 column 7

Could well be that my self-compile was bad. I don't know how to run the make tests with MXE tho.
