fsolve documentation does not have any description for info=-2. EXITFLAG in
the example below is info.   

Example 

func=@(x) 0;
X0=0;
[X,FVAL,EXITFLAG,OUTPUT,JACOB] = fsolve(func,X0)

results: 

X = 0
FVAL = 0
EXITFLAG = -2
OUTPUT =

  scalar structure containing the fields:

    iterations = 1
    successful = 0
    funcCount = 2

JACOB = 0
