I am creating model OF REED SOLOMON CODE WITH OVERLAPPED SYMBOL AND USING ROTATE REGISTER IN SIMULINK.
i GET THIS ERROR "Function 'bitrol' is not defined for a first argument of class double."
CAN ANYONE TELL ME MEANING OF THIS ERROR.

Hi,

Bitwise operators operate only over integer (fixed point) variables or arrays. Your variable is a (double precision) floating point and for this reason you get the error.
Please look at the help with "doc datatypes" in the Matlab command window.
