About embedded function inside simulink

I am stranger in simulink. Cp=5193 is just a number. 'Cp' is globally declared in Matlab embedded function.It is defined as signal in model explorer with datatype ->double, complexity-> real, dimension->2 In edit -> data port manager -> it is defined as parameter with size [1 1]

Error:

1.Expression 'Cp' for initial value of data 'Cp' (#61) must evaluate to a numeric or logical.

2.Error reported by S-function 'sf_sfun' in 'PBR_Temp_Xe/Embedded MATLAB Function/ SFunction ': Stateflow Suppress Error

you can't déclare a global variable in embedded function . you have to pass it through inputs argument. for now a compiler don't allow globals variables
