MTensor_getMTensor (C Function)

gets a subtensor element from an MTensor.

Details

Used in C/C++ code in a library function called from the Wolfram Language.
Uses the same numbering scheme as the Wolfram Language 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.

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);
