Extract row from Deedle and convert to Matrix

Question

I am trying to extract a row from a Deedle Frame and convert it to a flat (1x4) DenseMatrix. All missing values have been dropped and the values in the Frame are numerical.

My code:

let matrix =
    let curr = seq { yield frame.GetRowAt(10).As<float>() |> Series.values }
    DenseMatrix.ofSeq curr

produces the error:

error FS0192: internal error: convMethodRef: could not bind to method

It is interesting to note that also:

let try2 =
    let mySeq = seq { yield seq { 1.0 .. 10.0} }
    DenseMatrix.ofSeq mySeq

produces the same error.

I have updated to 11.0.061030.00 (update 4) with .Net 4.5.50709, but still facing the same issue.

Answer 1

Are you referencing Math.NET Numerics v2 or v3?

In v3 there is no DenseMatrix.ofSeq but instead DenseMatrix.ofColumnSeq and DenseMatrix.ofRowSeq.
