void nrm2(unsigned int p_n, hls::stream<WideType<t_DataType,(1<<t_LogParEntries)>>& p_x, t_DataType& p_res)

nrm2 function that returns the Euclidean norm of the vector x.

Parameters:

t_DataType the data type of the vector entries
t_LogParEntries log2 of the number of parallelly processed entries in the input vector
t_IndexType the datatype of the index
p_n the number of entries in the input vector p_x, p_n % (1<<l_LogParEntries) == 0
p_x the input stream of packed vector entries
p_res the nrm2 of x
