cblas_dgemm error in NativeBLAS #54

Open adamklein opened 12 years ago

adamklein commented 12 years ago

If I do:

val m1 = DenseMatrix.rand(10,10) val m2 = DenseMatrix.rand(10,10) m1 * m2

I get:

TransA must be 111, 112 or 113, but is set to -1TransB must be 111, 112 or 113, but is set to -1Parameter 2 to routine cblas_dgemm was incorrect ERROR in F2J JNI: getTrans() got n

and then JVM crashes silently. I have no trouble running MTJ or jblas code. Any ideas?

looks like it's a bug in netlib, from what I can tell. we're passing in a "n" to tell it to not transpose the matrices, but it's somehow mapping "n" to -1 instead of 111.
