Find the minimum of this function using ga. Get rng default % For reproducibility x = ga(@ps_example,2) ga stopped because the average change in the fitness value is less than options.FunctionTolerance. x = 1
Find the unconstrained minimum of the objective, starting from the point[0,0]. Return the solution,x, the objective function value at the solution,fun(x), the exit flag, and the output structure. x0 = [0,0]; [x,fval,exitflag,output] = patternsearch(fun,x0) patternsearch stopped bec...
Minimize the function f(x)=3x21+2x1x2+x22−4x1+5x2. To do so, write an anonymous function fun that calculates the objective. Get fun = @(x)3*x(1)^2 + 2*x(1)*x(2) + x(2)^2 - 4*x(1) + 5*x(2); Call fminunc to find a minimum of fun near [1,1]. Get x...
This MATLAB function finds a local minimum, x, to the function handle fun that computes the values of the objective function.

Find Minimum Location and Function Value Copy Code Copy Command Find the location of the minimum of sin(x) and the value of the minimum for 0<x<2π. Get fun = @sin; [x,fval] = fminbnd(fun,1,2*pi) x = 4.7124 fval = -1.0000 Obtain All Information Copy Code Copy Command Ret...
ga - Find minimum of function using genetic algorithm 从说明文档中函数的定义可以看出,ga函数是求解函数最小值的,故我们的函数可以定义成代价函数。 函数形式: x = ga(fun,nvars,A,b,Aeq,beq,lb,ub,nonlcon,options) x = ga(fun,nvars,A,b,[],[],lb,ub,nonlcon,IntCon,options) 【ga参数含义】 ...
多看MATLAB 帮助就好了， fminbnd： Find minimum of single-variable function on fixed interval 在固定间隔内寻找单变量函数的最小值。f指函数，min指最小值，bnd指“band”带宽，即固定某个间隔内。另外，max是最大值，poly是多项式的意思，polynomial。val是值的意思，value。polyval（P,X）是...
MATLAB优化问题中核心是要掌握fmincon函数。官方解释为:“Find minimum of constrained nonlinear multivariable function”。关键词为:约束,非线性。 可解决的问题形式化表述如下: \min_{x}f(x)\\such \ that \begin{cases}c(x)&\le&0\\ceq(x)&=&0\\A\times x&\le&0\\ ...
