- Update to version 1.3.0:
* New functions:
idxmatrix: creates a matrix with each element corresponding to
its subindex in the matrix.
hc2ind: Hilbert curve to linear indices
* The function publish has been removed from the miscellaneous
package because it is now released with Octave core since
version 4.2. Note that it's API is slightly different.
* The package is no longer dependent on the general package.
* pkg update for octave 5.1+ functionality
