Hi, it seems that DimensionalData and AxisKeys have quite a bit overlap. What are the considerations I should keep in mind for choosing between these two packages?

Is there a more succinct way to do this? ka = KeyedArray( ones(2,2), I=\[:a,:b\], J=\[:x,:y\] ) @tullio x\[i,j\] := ( ka\[i,j\], axiskeys(ka)\[1\]\[i\], axiskeys(ka)\[2\]\[j\]) Something like @tullio x\[i,j\] := ( ka(i,j), i, j ) T…

Hi all! I’m plotting a mesh made using MarchingCubes.jl and want to readjust the axis tick labels. Currently, the values just represent how many cubes there are along each dimension (e.g. 0:11 x 0:11 x 0:11), but I want …

Vectorised operations on regular arrays produce a cross product across dimensions. e.g. x = \[1 2 3\] a = reshape( x, (3,1,1)) b = reshape( x, (1,3,1)) c = reshape( x, (1,1,3)) X = @. a + b + c X\[3,3,3\] # =9 Simila…

Is it possible to connect data structures, similar to Primary-Key Foreign-Key connections in a relational database? One way could be to have a type similar to enum that would limit a field to a given set of values. Usi…

Sometimes I do not remember the position of dimensions or of the individual indexes in a multi-dimensional array and when performances are not a critical factor I prefer to work on keys rather than position. I am hence …
