Constructing PDSparsMat from Symmetric{Float64,SparseMatrixCSC{Float64,Int64}}

[Jan-van-Waaij]

Dear all,

Is there a reason why I cannot do the following:

A = sparse([1,2],[1,2],[1.0,1.0])
B = Symmetric(A)
C= PDSparseMat(B)

This gives the following error:

MethodError: Cannot convert an object of type Symmetric{Float64,SparseMatrixCSC{Float64,Int64}} to an object of type PDMats.PDSparseMat

Best wishes,

Jan

This does work for dense matrices, so it might be a good method to add. For now, at least for Julia v0.6 I see the following options work:

C = PDSparseMat(A)

C = PDSparseMat(cholfact(B))

Note that in Julia v0.7+ cholfact becomes chol.

Dear jkbest2,

Thanks for the reply! Would be great indeed if there is way to work around it.

Best,

Jan
