Matlab的fminsearch的numpyscipy类似物

Matlab的fminsearch的numpy / scipy类似物

这只是从Matlab语法到python语法的直接转换：

import scipy.optimizebanana = lambda x: 100*(x[1]-x[0]**2)**2+(1-x[0])**2xopt = scipy.optimize.fmin(func=banana, x0=[-1.2,1])

输出：

Optimization terminated successfully.         Current function value: 0.000000         Iterations: 85         Function evaluations: 159array([ 1.00002202,  1.00004222])
