    Hi, while trying to solve equations with unknowns using fsolve, I
    encounter this problem:

    Conditioning of Gradient Poor - Switching To LM method
    Maximum number of iterations exceeded
    Increase OPTIONS.iterations

    How to increase options.iterations in the following program??
    for instance:

    x0=[.5 .5 .5 .5 .5]; % initial guess of m, A, T, ws, wu
    options = optimset('Largescale', 'off', 'maxfunevals', 100000000);
    %switch off large-scale algorithm
    val = fsolve('fun3',x0,options); % calls the function 'fun3', i.e the
    necessary and sufficient conditions (5 equations)

  2. options.iterations will have no effect on any
    tool in the optimization toolbox.

    However, had you typed


    at the command line, you might see a reference
    to "maxiter". I'll bet it might do what you
