Is there an equivalent to Octave's "lookfor" command in Julia?

How to seek a concrete function in Julia? lookfor would make it in Matlab / GNU Octave, how can it be done here?

Solution

  • The equivalent of lookfor is apropos:

    julia> apropos("fourier transform")
Base.DFT.fft

julia> apropos("concatenate")
Base.:*
Base.hcat
Base.cat
Base.flatten
Base.mapslices
Base.vcat
Base.hvcat
Base.SparseArrays.blkdiag
Core.@doc

    Other useful functions, depending on what you're looking for, include methodswith, which can give you a list of methods that are specified for a particular argument type:

    julia> methodswith(Regex)
25-element Array{Method,1}:
 ==(a::Regex, b::Regex) at regex.jl:370                                                                
 apropos(io::IO, needle::Regex) at docs/utils.jl:397                                                   
 eachmatch(re::Regex, str::AbstractString) at regex.jl:365                                             
 eachmatch(re::Regex, str::AbstractString, ovr::Bool) at regex.jl:362
