MATLAB: Is it possible to assign arrays with different length for LUT parameters in generated code than in Simulink

Question

Hi,

I intend to generate C-Code out of my simulink model using Simulink Coder (ert.tlc). I wish to tune certain parameters of simulink model and for this reason, i have created simulink objects with "ImportedExternPointer" storage class.

While compiling and generating the code, the length of arrays for breakpoint and table data of a particular lookup table was 15000. I wish to tune these parameters, not just by the values, but also by the length of these arrays. I hoped that defining them as pointers would allow me to do so. However in the code, the function for lookup table looks as follows

real_T look1_bftfId_binlagpw(real_T u0, const real32_T bp0[], const real32_T
  table[], uint32_T maxIndex)

and correspondingly, the code snippet for the relevant lookup table is as below.

look1_bftfId_binlagpw
        (InputSignal->Timing.t[0], BreakpointData,
         TableData, 15000U)        

Is there a way to remove this restriction and give different sized array as inputs?

Thanks and best regards,

Karthik
