Right now I use three different functions to assign the three individual values to the variable button_choice, which strikes me as fairly inefficient. Is there a way that I can create a single function 'press_b
Suppliedobjective function must return a scalar value. To run the above matlab code, when K=1, i can have only one value i=1, then parameter values can be taken as follows. A=3.5153e+21;eta = 1; H_DL = 1.0e+02 * [ 7.3460 + 2.3079i; 2.0984 - 3.5173i; 4.7...

Allows any number of output arguments from a function. The variable varargout is a cell array containing the optional output arguments from the function. varargout must be declared as the last output argument and must contain all the outputs after that point onwards. In the declaration, varargout...

for i=1:1:n k=k+E*A*x(i)^2/L;end return k;在这个函数中,我们定义了变量k,它被初始化为0。接下来,我们使用for循环从1遍历到n,每次迭代时,我们将E、A、x(i)和L的乘积累加到k中。这里,x(i)表示x的第i个元素。需要注意的是,x(i)^2表示x的第i个元素的平方,这是计算公 ...
