void gbmv(const unsigned int p_m, const unsigned int p_n, const unsigned int p_kl, const unsigned int p_ku, const t_DataType p_alpha, hls::stream<WideType<t_DataType, t_ParEntries>>& p_M, hls::stream<WideType<t_DataType, t_ParEntries>>& p_x, const t_DataType p_beta, hls::stream<WideType<t_DataType, t_ParEntries>>& p_y, hls::stream<WideType<t_DataType, t_ParEntries>>& p_yr)

The gbmv function performs general banded matrix-vector multiplication matrix and a vector y = alpha * M * x + beta * y.

Parameters:

t_DataType The data type of the vector entries.
t_ParEntries The number of parallelly processed entries in the input vector.
t_MaxRows The maximum size of buffers for output vector.
t_IndexType The datatype of the index.
t_MacType The datatype of the output stream.
p_m The number of rows of input matrix p_M.
p_alpha scalar alpha
p_M The input stream of packed Matrix entries.
p_x The input stream of packed vector entries.
p_beta Scalar beta.
p_y The output vector.
