    Call to dgesv/sgesv not returning expected result

    NTDeveloper

      I'm quite new to using the ACML so I'm sure this can be chalked up to user error. I would appreciate some direction on what I'm doing wrong. All calls to either dgesv/sgesv return with the info parameter set to 2. Here is one such example:

      int _ipiv;
      int _info;
      float A[4]; //2x2 identity matrix
      A[0] = 1;
      A[1] = 0;
      A[2] = 0;
      A[3] = 1;

      float B[2];
      B[0] = 1;
      B[1] = 1;

      ::sgesv(2, 1, A, 2, &_ipiv, B, 2, &_info);
      //Upon return, _info is set to 2
      ?
