MTensor_setComplex (C Function)

sets a single element of an MTensor of complex type.

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 the rank of .
  • Will cause an error to be launched if the element does not exist, or if the tensor is not a complex MTensor.

Examples

Basic Examples  (1)

This sets the element in a complex-valued matrix at position (1,1) to be I:

MTensor T0;
mint lens[2];
mcomplex z = {0.,1.};
int err;
...
lens[0] = 1;
lens[1] = 1;
err = libData->MTensor_setComplex( T0, lens, z);
