How to manually set Initial Solution for CPLEX solver MATLAB for LP problem?

  • 1.  How to manually set Initial Solution for CPLEX solver MATLAB for LP problem?

    Hi,

    I am trying to supply, initial guess for CPLEX in MATLAB(2019b) using the following syntax.

    Y = cplexlp(f, Aineq, bineq, Aeq, beq, lb, ub, x0) .
    I gave x0 to my linear programming problem. when, I am trying different initial guess, after simulation I didn't see change in output.
    For example, if I give x0= zero and x0= one. I see that output is same x0=6.6. I get the same output even,if i dont supply any initial guess to my problem as well.
    In my optimization problem, AX<=B, A has '114 X 48 matrix ',  B has '114 x 1 matrix'.  My system has under-determined system, So how I need to supply the initial guess for "LP Problem" in MATLAB
