vsip_dvmeansqval_p - Compute Mean of Squared Values

Core

vsip_scalar_f vsip_vmeansqval_f(vsip_vview_f const *a); 
vsip_cscalar_f vsip_cvmeansqval_f(vsip_cvview_f const *a);

This function computes the mean of the squared values of all elements in a vector. The mean of squared values is calculated as:

1 n∑︁-1 mean_sq= -- |ai| 2 n i=0

where $n$ is the length of the vector and $ai$ are the elements of the input vector.

vsip_dvview_p const* a: Input vector for which to compute the mean of squared values.
