This manual is preliminary and incomplete.
While our Core implementation implements all functions given in the standard we are still working on completing this documentation.

Please refer to the VSIPL standard for a complete function reference of the Core profile until we have completed work on this documentation.

5.5.1 vsip_vhisto_p - Compute Histogram of a Vector View

typedef enum _vsip_hist_opt { 
  VSIP_HIST_RESET = 1, 
  VSIP_HIST_ACCUM = 2 
} vsip_hist_opt; 
 
void vsip_vhisto_f(const vsip_vview_f *src, vsip_scalar_f min_bin, 
                    vsip_scalar_f max_bin, vsip_hist_opt opt, 
                    const vsip_vview_f *hist);

Description

This function computes the histogram of the elements in the vector view src and stores the result in the vector view hist. The histogram is computed over the range [min_bin, max_bin] with the specified binning options opt.

Parameters

const vsip_vview_p* src: Pointer to the source vector view.
vsip_scalar_p min_bin: The minimum value of the histogram bins.
vsip_scalar_p max_bin: The maximum value of the histogram bins.
vsip_hist_opt opt: Options for histogram computation.
- VSIP_HIST_RESET - Reset histogram and compute new
- VSIP_HIST_ACCUM - Accumulate with previous
const vsip_vview_f* hist: Pointer to the destination vector view where the histogram will be stored.

Example

vsip_vview_f *src_vector_view; 
vsip_scalar_f min_bin = 0.0; 
vsip_scalar_f max_bin = 10.0; 
vsip_hist_opt hist_options = VSIP_HIST_ACCUM; 
vsip_vview_f *hist_vector_view; 
 
// Assuming src_vector_view and hist_vector_view have been properly initialized 
vsip_vhisto_f(src_vector_view, min_bin, max_bin, hist_options, hist_vector_view);
