I am using lsqcurvefit inside large nested for loops. The following messages are printed in the command window thousands or sometimes millions of times.
Message:
Local minimum found. Optimization completed because the size of the gradient is less thanthe default value of the function tolerance.
stopping criteria details>
The question is how can I suppress these messages?

Have you tried setting the 'Display' option?
opts = optimset('Display','off');
... = lsqcurvefit(...,opts);

Hi I tried this and I just get and error because lsqcurvefit is expecting lower or upper bounds

That is beucase, options comes after the Lower and Upper bound entries in the syntax. So the below would be helpful: ...=lsqcurvefit(fun, [1 2 3], xdata,ydata,[ ],[ ],opts);

using options in the lsqcurvefit function can work:
options=optimset('Display','off');
thanks Matt!
