gets a subtensor element from an MTensor.

Details and OptionsDetails
  • Used in C/C++ code in a library function called from Mathematica.
  • Uses the same numbering scheme as Mathematica parts, i.e. the first element is 1.
  • The array is assumed to have length at least equal to .
  • A nonzero error code value will be returned if the element does not exist or if the rank of is not at least as big as .
  • The destination * should either be null (0) or an MTensor allocated with MTensor_new.

    Basic Examples  (1)

    This gets the element at position 1,1 copying into an MTensor result:

    MTensor T0, T1 = 0;
    mint lens[2];
    int err;
    lens[0] = 1;
    lens[1] = 1;
    err = funStruct->MTensor_getMTensor( T0, lens, 2, &T1);
