When I try to run the code, I get the error as below, "Undefined function or variable 'res_parameters'. Error in TBQ_box_f (line 5) [res,block,nums,fluid]=res_parameters; Error in Project_1_Main (line 11) [ T, Q,B] = TBQ_box_f(BC,P_B,para_wells,q_well); %a box that spits out matrices T, B, Q" Can you please guide me on how I can go about this error. Thank you
