CPLEX instantiation and MATLAB issue

I am creating an empty CPLEX instant in MATLAB and notice the following errors includined in the model stucture. Can anyone help with the meaning of these?

clear all
cplex = Cplex()
     
ans=
     
   Cplex handle
     
   Properties:
      Model: [1x1 struct]
      Param: [1x1 struct]
      DisplayFunc: @disp
     
   Methods, Events, Superclasses
>> cplex.ERROR_INCORRECT_ARGUMENTS

ans =
    'Incorrect arguments type.'
>> cplex.ERROR_INCORRECT_PATH
ans =
    'Could not open file cplexlink12100.%s. Please update your path.'
>> cplex.ERROR_OUTPUT_ARGUMENTS
ans =
    'Incorrect number of output arguments.'
>> cplex.ERROR_TOO_FEW_ARGUMENTS
ans =
