Subject Re: Returning breeze.linalg.DenseMatrix from method
Date Mon, 17 Nov 2014 15:04:49 GMT
Yeah, it works.

Although when I try to define a var of type DenseMatrix, like this:

var mat1: DenseMatrix[Double]

It gives an error saying we need to initialise the matrix mat1 at the time
of declaration.
Had to initialise it as :
var mat1: DenseMatrix[Double] = DenseMatrix.zeros[Double](1,1)

Anyways, it works now
Thanks for helping :)
