Constrained structs with automatic parameter handling
A struct whose fields carry constraints (a positive scalar, a vector on the simplex, a correlation matrix) needs a constructor that rejects invalid values, and a bijection between the constrained set and Rp so that optimizers and samplers can work…

Raised-cosine pulse shaping in Julia
MATLAB's rcosdesign(beta, span, sps, shape) designs a (root-)raised-cosine FIR pulse-shaping filter. Julia's DSP.jl has no direct equivalent, but SignalAnalysis.jl provides both shapes as thin wrappers over DSP.digitalfilter: | MATLAB | SignalAnalysis.jl | |---|---| | rcosdesign(β, span, sps, 'normal') | rcosfir(β,…
