Member Function Documentation

void lama::LAMAArrayUtils::assign ( _LAMAArray &  target,
const _LAMAArray &  source 
) [static]

Static method for LAMAArray assignment with type conversions.

Parameters:
[out]targetcontains copy of source values
[in]sourcearray with source values
  LAMAArray<float> fvalues;
  LAMAArray<double> dvalues;
  ...
  dvalues = fvalues;   // not supported
  assign( dvalues, fvalues );  // supported

Size of target array will be the same as the source array.

Todo:
Exact specification at which context values will be copied or add context arg
