C++ (Cpp) random_laplace Examples

Example #1

File: random.c Project: npd/imscript

static double random_exponential(void)
{
	//double u = random_uniform();
	//double r = -log(1-u);
	//return r;
	return fabs(random_laplace());
}

Example #2

File: functions.c Project: Ghnuberath/gnumeric

static GnmValue *
gnumeric_randlaplace (GnmFuncEvalInfo *ei, GnmValue const * const *argv)
{
	gnm_float a = value_get_as_float (argv[0]);

        return value_new_float (random_laplace (a));
}

Example #3

File: random-generator.c Project: Ghnuberath/gnumeric

static gboolean
tool_random_engine_run_laplace (data_analysis_output_t *dao,
				tools_data_random_t *info,
				laplace_random_tool_t *param)
{
	int i, n;
	for (i = 0; i < info->n_vars; i++) {
		for (n = 0; n < info->count; n++) {
			gnm_float v;
			v = random_laplace (param->a);
			dao_set_cell_float (dao, i, n, v);
		}
	}
	return FALSE;
