Save DenseMatrix to text file

[Alex Minnaar]

Hi.  Could someone suggest the best way to save a DenseMatrix to a text file.  I have tried

val writer = new PrintWriter(new File("test.txt" ))

writer.write(new DenseMatrix[Double](K, vocabSize, Gamma(100.0, 1.0 / 100.0).sample(K * vocabSize).toArray).toString)

writer.close()

But it seems to write a truncated version of the matrix (i.e. one with "...")

So if someone could shed some light on this for me, that would be great.

Thanks,

Alex

val dm = // ...

breeze.linalg.csvwrite(new File("text.txt"), dm, separator = ' ')

should do it.

Also, DenseMatrix.rand(K, vocabSize, Gamma(100.0, 1.0 / 100.0)) ought to work for making the matrix
