Core

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.

3.1.4 vsip_dvrandn_p - Fill Vector with Normally Distributed Random Numbers

void vsip_vrandn_f(vsip_randstate *state, const vsip_vview_f *r); 
void vsip_cvrandn_f(vsip_randstate *state, const vsip_cvview_f *r);

Description

This function fills a vector with random numbers drawn from a standard normal distribution (mean = 0, standard deviation = 1) using the specified random number generator state. The random numbers are generated according to the normal (Gaussian) probability density function:

1 -x2 f(x)=⎷2-πe 2

Parameters

vsip_randstate* state: Pointer to the random number generator state.
const vsip_dvview_p* r: Pointer to the output vector that will be filled with normally distributed random numbers.

Example

vsip_randstate *rand_state; 
vsip_vview_f *random_vector; 
 
// Initialize random number generator state 
rand_state = vsip_randcreate(42, 0, 1, VSIP_PRNG); 
 
// Assuming random_vector has been properly initialized 
vsip_vrandn_f(rand_state, random_vector); 
 
// Clean up 
vsip_randdestroy(rand_state);
