Dear all,
I get the following message but the code seems to be working ok
In fmincon (line 797)
Warning: Matrix is singular to working precision.
Is there a way to rectify this problem?

Hi there,
Do you have a solution for this ? Would computing the derivatives yourself solve the problem ?

Options:
TypicalX Typical x values. The number of elements in TypicalX is equal to the number of elements in x0, the starting point. The default value is ones(numberofvariables,1). fmincon uses TypicalX for scaling finite differences for gradient estimation.
