4.2.4 vsip_dvmeanval_p - Compute Mean Value of Vector

vsip_scalar_f vsip_vmeanval_f(vsip_vview_f const *a); 
vsip_cscalar_f vsip_cvmeanval_f(vsip_cvview_f const *a);

Description

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

where is the length of the vector and 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.
