FiniteDifferenceStepSize 有限差分步长 有限差分的标量或向量步长因子。当设置FiniteDifferenceStepSize为向量v时,正向有限差增量是 delta = v.*sign′(x).*max(abs(x),TypicalX), 当 sign′(x) = sign(x) except sign′(0) = 1 中心有限差分为 delta = v.*max(abs(x),TypicalX) 标量FiniteDifferenceS...
7. 误差容限(Tolerance) 在进行数值计算和优化问题时,误差容限是指允许的计算误差范围。通过设置合适的误差容限,可以控制计算的精度和稳定性。 8. 平滑因子(Smoothing Factor) 在信号处理和图像处理中,平滑因子是一种控制平滑程度的参数。通过调整平滑因子的大小,可以在保留信号的主要特征的同时,去除噪声和干扰。 9....
It is stopping because it reached one of the criteria for stopping. Adjust thestep size toleranceif you want it to continue. The default is1e-6. When adjusting, take into consideration thistip: "Generally set tolerances such asOptimalityToleranceandStepT...
No feasible solution found. fmincon stopped because the size of the current step is less than the default value of the step size tolerance but constraints are not satisfied to within the default value of the constraint tolerance. <stopping criteria details> x = 1.0e+03 * 4.666024308553983 3.8572...
提示No solution found.fsolve stopped because the relative size of the current step is less than the default value of the step size tolerance, but the vector of function values is not near zero as measured by the default value of the function tolerance.查了很多资料不清楚哪里出的问题,求各位...
default value of the step size tolerance squared, but the vector of function values is not near zero as measured by the default value of the function tolerance. <stopping criteria details> 问题解决: 在命令行窗口键入x 得到x 1.2114 修改原代码x初值为1.2114 ...
fmincon stopped because the size of the current step is less than the default value of the step size tolerance and constraints are satisfied to within the default value of the constraint tolerance. Optimization stopped because the relative changes in all elements of x are less than options.StepT...

1、打开MATLAB，file-new-script，进行程序编制，例如这里画一条曲线。”clear;clc;m=1365;a=-11825/m+5.01;x=0:0.1:1.6;b=a-log10(x);y=10.^(b);p=plot(x,y,'r');”2、运行程序，可以先保存在运行，进行“save and run”，也可以拷贝到command window运行。3、运行后得到图形。
