    shift left/shift right in VHDL

    Thanks for the reply.. you are right..but this is the case when you have single variable std_logic_vector, in my case its a matrix of 4x1. Variable x : matrix_4x1 := ("000000100", "0000000000", "0011110000", "0010110001"); how can i shift each row of this matrix?
