How do I create two "nullclines" of these equations in matlab? I'm unable to find any information on nullclines in coding anywhere.

A simple model of glycolysis proposed by Sel'kov has the form Here a and b are two parameters. x and y are variables. All parameters and variables are assumed to be non-negative. I. Consider the scenario when a=0.06 and b=0.6.
