Copying 2D Histograms
- Function: int gsl_histogram2d_memcpy (gsl_histogram2d * dest, const gsl_histogram2d * src)
-
This function copies the histogram src into the pre-existing
histogram dest, making dest into an exact copy of src.
The two histograms must be of the same size.
- Function: gsl_histogram2d * gsl_histogram2d_clone (const gsl_histogram2d * src)
-
This function returns a pointer to a newly created histogram which is an
