passing a cell array structure to matlab function

hi,

I am using matlab function block in Simulink. I have to pass a structure as input to the function. I have changed the type to parameter in model explorer. While executing i received the error " Error using sf MATLAB class 'cell' found at 'ctx.S' is unsupported."

I tried converting the cell array to character array and then used the character array(instead of entire structure) as input to the function. In this case i got error " Error using sf Expression 's' for initial value of data 's' (#51) must evaluate to a numeric or logical"

ctx is the structure i am using.

i assigned the structure fields as s =ctx.S

ctx.S is a cell array of hexadecimal values stored as strings.

I want to have the data as hexadecimal inside the function.How do i pass the values in ctx.S to the matlab function used in Simulink?

Thanking you in advance.

Simulink does not support cell arrays or strings as data types for signals. Anything you want to pass to another block as a signal must be in numeric form (or logical).
