fnint(f,value)中的value参数用在matlab函数的逻辑运算时，表示逻辑运算的“非”，用在输出参数时表示不输出某个参数。如：例1：a=magic(5);b=randi(10,5,5);c=or(a,~b)例2：a=magic(5);b=randi(10,5,2);[m,~]=size(a*b)矩阵乘法：A*B，A 和 B 的矩阵乘法，A 的列数必须和...
In general, you should define a default value on the root level so that all subsequent plotting functions use those defaults. Specify the root in set and get statements using the groot function, which returns the handle to the root. You can define default property values on three levels: ...
mustBeNonempty(value) throws an error if value is empty. This function does not return a value. mustBeNonempty calls the following function to determine if the input is nonempty: isempty Class support: All MATLAB® classes exampleExamples...
The function call deletes the plot. However, it does not affect the background color of the figure. Get clf Now, reset the figure properties and return the children of the figure. clf('reset') resets the background color to its default value. Get f = clf('reset'); f.Children ...

Call the nexttile function to create the axes objects ax1 and ax2. Create separate line plots in the axes by specifying the axes object as the first argument to plot3. Get tiledlayout(1,2) % Left plot ax1 = nexttile; t = 0:pi/20:10*pi; xt1 = sin(t); yt1 = cos(t); plot3...

In some representations, it is necessary to carry out previous steps for the function to work correctly. pie and pie3: If you useLaTeXinterpreter with default labels (percentage) you need to fix the plot before call setfigpaper. Solution: ...
functionf=objfun(x)f=exp(x(1))*(4*x(1)^2+2*x(2)^2+4*x(1)*x(2)+2*x(2)+1); Step 2: Set options. 设置选项以使用“quasi-newton”算法。 设置选项是因为“trust-region”算法要求目标函数包含渐变。 如果您没有设置选项,那么根据您的MATLAB®版本,fminunc可以发出警告。
