The following two attempts at constructing matrices where entries have different units both fail with the same error, but at different stages of the process. The first example I can...
It would be nice to have a mechanism to impose stability of an estimated Koopman operator. One such mechanism which is commaonly employed for subspace-based identification is https://www.researchgate.net/publication/3891703_Imposing_stability_in_subspace_identification_by_regularization for which...
It appears as if providing a custom julia script `precompile.jl` with statements to execute has no effect on the buildt system image. I believe this is due to the command-line...
I can't seem to figure out how to make use of the sympy `MatrixSymbol` type, described at http://docs.sympy.org/latest/modules/matrices/expressions.html I would like to manipulate matrix expressions on a block matrix level,...
The current way of constructing `Vcat` objects, by splatting/slurping, causes stack overflow when concatenating a large number of arrays since special methods of these functions are compiled for the particular...
The following model (a simplified version of https://github.com/TuringLang/Bijectors.jl/issues/169) throws a method error with v0.18.0 of Turing ```julia using LinearAlgebra using Turing q_m = randn(6,100) trq_m = randn(6,100) qd_m = randn(6,100)...
I'm getting a method error when trying to run ```julia using Turing: Variational m = clamp_sim(trq_m, q_m) advi = ADVI(10, 1000) q = vi(m, advi) ``` where `clamp_sim` is a...
I get results like ```julia julia> HomotopyContinuation.evaluate(constraints, (Dict(f.variables .=> real.(sol)))) 8-element Vector{Expression}: -1.77635683940025e-15*-0.235475 -0.929620778338419*-0.222360917086043 -3.00918102352667*-0.198144357487694 -8.44189647517252*-0.1555001812606 -28.9660551738096*-0.0884901134798353 -276.162595297163*-0.0162316466214997 -70.7686049843743*-0.0896340387513346 -2.98369032774388*-1.025 ``` which seems strange, why wouldn't this return numerical values?...
I got confused by the following query ```julia metrics = @from i in data0 begin @where i.happy != "NA" && i.energetic != "NA" && !ismissing(i.ActualStartTime) @select {i.ParticipantID, happy=round(Int, i.happy), energy=round(Int,...
