Add complex valued bandpass filter

7

This pull request allows to create ComplexBandpass filters for one sided pass bands (different pass bands for positive or negative frequencies) I haven't implemented `scalefactor(coefs::Vector, ftype::ComplexBandpass)` yet, as I'm not...

How to handle user defined functions?

2

I get the following error ```julia ERROR: MethodError: no method matching calc_A(::VectorizationBase.SVec{16,Int16}) ``` where `calc_A` is a user defined function. Do I need to implement `calc_A(::VectorizationBase.SVec{16,Int16})` myself? Why isn't there...

Multiply 2 16-bit integers and accumulate to 32-bit integer

10

How would I multiply 2 16-bit integers and accumulate to 32-bit integer? Something like `_mm_madd_epi16` So far the result of the multiplication seems to be done in 16-bit: ```julia a...

100x Performance regression with @fastmath in combination of two units with different types (Float and Int)

4

Here is MWE: ```julia import Unitful: Hz, MHz function accumulate_phase(f0, fs) phase_accu = 0.0 @fastmath for i = 1:4000 phase_accu += f0 * i / fs end phase_accu end ```...

Slow for large matrices

4

I am implementing a Kalman filter and I observed that for large matrices it gets considerably slower. Consider these two functions: ```julia function time_update(x, P, F, Q) x_next = F...

Support Rdiv with broadcasting

1

```julia H = [1., 0.]; S = [2. 0.; 0. 1.]; A = Array{Float64, 2}(undef, 1, 2); A .= Mul(H', Inv(S)) .* 1. ``` Output: ```julia ERROR: MethodError: no method...

Allocation-free matrix multiplication with more than two matrices

1

Could this be made allocation-free? ```julia function test(S, H, P, R) S .= Mul(H, P, H') .+ R end H = ones(2,2); P = ones(2,2); R = ones(2,2); S =...

Document that for spherical coordinates theta is going from x to y and phi is going from xy-plane to z

17

Document that for spherical coordinates theta is going from x to y and phi is going from xy-plane to z. This definition of phi differs from the mathematically defined phi:...

[FR] Unicode barplot

2

I'd like to have the beautiful bar plots from Unicodeplots:  I tried: ```julia using Plots unicodeplots() y = randn(6) * 2 .+ 45 bar(1:6, y, legend = false, orientation...

If I define a custom time scale inside a package, conversion will not work: ```julia module FooBar using AstroTime @timescale GPSTime TAI AstroTime.Epochs.getoffset( ::GPSTimeScale, ::InternationalAtomicTime, second, fraction) = 19 AstroTime.Epochs.getoffset(...
