I eventually got stuck with MATLAB'sfzerofunction. The user's code was calling it billions of times on rather simple functions which revealed overheads that nobody had reported before. I had a chat with development who did some fixes andin R2022a,fzerowas made around 3x faster than beforefo...
Open in MATLAB Online f = @(x) 5*sin(1.9*x)+2.1*sin(9.1*x);%from above y = f(linspace(0,100,2)); How many of the zeros do you detect in y? y = f(linspace(0,100,10)); How many of the zeros do you detect in this y?
一个MATLAB 函数应该是这样 function g = sigmoid(z)g = zeros(size(z));g=1./(1 + exp(-z));end 在方程末尾加入一行单独的 end 你没有声明变量F,你瞎用什么
Fx3 = zeros; Fy3 = zeros; Fx4 = zeros; Fy4 = zeros; y = @myfunction; end I read that in a matlab function block I have to define the output dimensions first and haope I can do this with the Fx1 = zeros. So far I always get the error that there is to less information and...

MATLAB Online에서 열기 I'm trying to transform a for loop from Matlab into python. I would like to create arrays of zeros and fill them via a for loop. In Matlab everything works perfectly, but in Python I have some problems The cycle is as follows: 테마복사 cell=30...

Here we see that we have cleared (i.e., deleted) A from memory, and assigned an empty matrix to B and a 4 × 4 array of zeros to C. Note that the size of matrices can also be determined using the size and length functions: ...
dy = zeros(3,1); % a column vectordy(1) = y(2) * y(3);dy(2) = -y(1) * y(3);dy(3) = -0.51 * y(1) * y(2);2、在command窗口输入options = odeset('RelTol',1e-4,'AbsTol',[1e-4 1e-4 1e-5]);[T,Y] = ode45(@rigid,[0 12],[0 1 1],options);plot(T,Y...
This line of reasoning establishes that it is not possible to construct a function that can tell you how many zeros any arbitrary function has. Sign in to comment.Sign in to answer this question.See Also MATLAB Answers How to check whether the fun...
