Yep. So 'C' and 'F' mean C (row-major) layout or Fortran (col-major) layout. Your guess was right about 'iadd' and 'isub': these are simply A += B and A -= B. The values of A and B are given by the "_matrix_" bits: the first one describes A, and the second describes B. So "test_matrix_slice_matrix_range_trans_isub_C_float32" means matrix_slice -= matrix_range.T where both are C-layout and single precision. > Hmm, these errors look definitely wrong. I'll have a look... OK. Of course if you need help or something decifered, e-mail me, or ping me on IRC.
