Transpose not working on Array{Any,2}


#1

transpose is not working for a specific matrix I have. Consider the last line in the code below.

Is this deliberate? am I missing anything here?

I can work around this, by using permutedims, but I would have expected transpose to work.

othermat=convert(Array{Any,2},rand(3,2))
transpose(othermat) #works

mat=Any["Correlation" 0.367298; "Std Dev Trn" 1.54907e-8; "Std Dev Val" 0.0115051;]

permutedims(mat,[2,1]) #works
permutedims(mat,(2,1)) #works

transpose(mat) #does not work on julia 0.6

This is intentional, but controversial. See https://github.com/JuliaLang/julia/issues/20978 for some discussion of whether or not it actually makes sense to get the error you’re seeing.

In the meantime, your permutedims() solution is perfectly good.

thank you.
