Dear Philip Chow

1. Disable Pre-Processing using the flags 'PreProcess','none' with optimoptions: ?options = optimoptions(@linprog, 'Preprocess', 'none');

[Walter Roberson]

Unfortunately the code it is failing in is buried in a .p file that contain a complete class.

Answer 1

[Adusumilli Bala Surendra]

Try the following: It worked for me.

Disable Pre-Processing using the flags 'PreProcess','none' with optimoptions;

options = optimoptions(@linprog, 'Preprocess', 'none');
