4.2.4 vsip_dvmeanval_p - Compute Mean Value of Vector

vsip_scalar_f vsip_vmeanval_f(vsip_vview_f const *a); 
vsip_scalar_d vsip_vmeanval_d(vsip_vview_d const *a); 
vsip_cscalar_f vsip_cvmeanval_f(vsip_cvview_f const *a); 
vsip_cscalar_d vsip_cvmeanval_d(vsip_cvview_d const *a);

Description

This function computes the arithmetic mean (average) value of all elements in a vector. The arithmetic mean is calculated as:

1n-∑︁1 mean = -- ai n i=0

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

Parameters

vsip_dvview_p const* a: Input vector for which to compute the mean value.

Return Value

Returns the arithmetic mean of all elements in the vector.
