In Simulink,I need to use one of the inputs to a function block in another saved function. So I want to decalre this input as global in the simulink but once i do that I get the following error.
Global declaration not resolved to a Data Store Memory block registered via the Ports and Data Manager.
Here the variable R is given as input and I want to declare this as a global variable and use it in a function which I am using in this model.

You do not need a Read Memory block. You need to create one Data Store Memory block for each global variable. The sequence is described at https://www.mathworks.com/help/simulink/ug/using-global-data-with-the-matlab-function-block.html#bsdud7d-1
You might need to do step 3 (Ports manager) for each different MATLAB Function Block you have that uses the global variable.
