I’m trying to read large datasets from HDF5 files into StaticArrays but I’m really struggling to understand how to get the data into a StaticArray. I’m using the following function to read the HDF5 file and it works fine, returning the expected data: function get_property(filepath::String, propert…

A matrix of size (3, 44843) is much too large for StaticArrays. The StaticArrays README says: Note that in the current implementation, working with large StaticArray s puts a lot of stress on the compiler, and becomes slower than Base.Array as the size increases. A very rough rule of thumb is that…

Thanks. I completely missed that statement about array size. It’s basically a matrix of forces (x,y,z) at nodes. There would be another set of points of (x,y,z) to provide the location of each node. I had been thinking I could implement something like the FieldVector example in the StaticArray docu…

If you want to use FieldVector just so you can access the x value with p.x, note that since StaticArrays 1.3, released 4 days ago, x/y/z/w field access is implemented for SVector and MVector as well: julia> using StaticArrays julia> p = SA[1.1, 2.2, 3.3] 3-element SVector{3, Float64} with indices …

Oh that is nice. Something for free!

If you read in a huge array and don’t want to create a copy with SVectors, you can also reinterpret the original array like reinterpret(S, arr) where S is your chosen point representation.

Yes that looks like the same as what Julius proposed, only that example is with different dimensions, an SMatrix from a 3D Array. Here it is written out for this case: julia> using StaticArrays julia> query = rand(3, 44843) 3×44843 Matrix{Float64}: 0.779144 0.664259 … 0.51808 0.953658 0.535…
