How to import your OMP function

[WillPowellUk]

Hi Sebastian,

I am struggling to import your code so that I can run your omp function.

I am sure there will be a more elegant solution but as of now I have included all the files locally, and then tried to run omp:

`include("CompressedSensing.jl-main/src/matchingpursuit.jl")
include("CompressedSensing.jl-main/src/util.jl")
include("CompressedSensing.jl-main/src/backward.jl")
include("CompressedSensing.jl-main/src/basispursuit.jl")
include("CompressedSensing.jl-main/src/exhaustive.jl")
include("CompressedSensing.jl-main/src/forward.jl")
include("CompressedSensing.jl-main/src/matchingpursuit.jl")
include("CompressedSensing.jl-main/src/oblivious.jl")
include("CompressedSensing.jl-main/src/sbl.jl")
include("CompressedSensing.jl-main/src/stepwise.jl")
include("CompressedSensing.jl-main/src/twostage.jl")
include("CompressedSensing.jl-main/src/CompressedSensing.jl")

omp(A, b, k)
However I am getting the erorLoadError: UndefVarError: SparseVector not defined` which I assume is a dependency from a file that is included later.

I apologies for my ineptidue in Julia but please advise.

Kind regards,
Will

Good question @WillPowellUk!

Did you try adding CompressedSensing to the package manager?

In the REPL (i.e. terminal), you can do this by first typing "]", which should change the context from "julia>" to pkg>. You can then type add CompressedSensing and hit enter:

julia>]
(@v1.9) pkg> add CompressedSensing

This should install all the required dependencies and might take a few minutes. After that is done, press "delete" to exit the package manager. You should see "julia>" again on the left in your terminal.

Now the final step:

julia> import CompressedSensing: omp

julia> A = randn(3, 4); b = randn(3);

julia> omp(A, b, sparsity=2)
4-element SparseArrays.SparseVector{Float64, Int64} with 2 stored entries:
  [1]  =  0.856756
  [2]  =  0.0834363

I apologize for the lack of clear documentation. This grew out of a grad school project of mine. If the above resolves your issue, I'll add it to the README.

@SebastianAment Thank you ever so much. Your instructions are very clear, and worked like a charm. I really appreciate you open sourcing this. Do add to the ReadMe to help others. Cheers!
