Detailed Description

Reduction operator that looks for the first element that is NaN or Inf and returns this index!

targ_obj <- { (v0_i,i) | RTOp_in_nan_inf(v[0](i)) }

This operator is defined to allow exactly one vecto arguments (num_vecs == 1) v[0] but can handle sparse or dense vectors. The element with the lowest index is selected so that the reduction object returned will be unique for a given vector.

Function Documentation

struct RTOp_ROp_find_nan_inf_reduct_obj_t RTOp_ROp_find_nan_inf_val ( RTOp_ReductTarget  targ_obj  ) 

Extract the number offending element.

If return.i == 0 then no element was found to be NaN or Inf.
