I want to find minimum for function in higher dimension. I found minf_lbfgs() in tensorlab but it requires me to give gradient. Are there any tools which give me result without calculating gradient.
x = fminsearch(fun,x0) works only when x is matrix (or less).

Usually, providing the gradient in MATLAB codes from the Optimization Toolbox is optional, but not necessary.
