If that is in seconds, the frequency will be in Hz. The best way to do that is: [y,Fs] = audioread('speech.wav'); % Return Sampling Frequency As The Second Output L = size(y,1); Fn = Fs/2; % Nyquist Frequency
and u is defined as given below *** functionpdex1 m = 0; x = linspace(0,1,20); t = linspace(0,0.5,5); sol = pdepe(m,@pdex1pde,@pdex1ic,@pdex1bc,x,t); % Extract the first solution component as u. u = sol(:,:,1); ...
>> t=linspace(0,2*pi,100); >> y=5*t.*(sin(t).^2)-t.^2*(cos(t).^2); Error using * Incorrect dimensions for matrix multiplication. Check that the number of columns in the first matrix matches the number of rows in the second matrix. To perform elementwise multiplication, use...
Star Strider has a point too. However with the values you have, linspace does not actually pass very close to -2 or 2. (Try linspace(-10, -0.05)). At least on my system there are no out of bounds values involved. However if I use:

When you called "ode45", you were only passing in a scalar value for the initial condition. However, it looks like your "odefun" expects a 3x1 solution vector at each time step and returns a 3x1 "dydt" vector. I don't know the details of the ODEs...

MATLAB Online에서 열기 hi, you have N=300 points for duration t=30 secs , then the samle rate is f=N/t=10Hz or you can perform this way : 테마복사 T=linspace(0,30,300); Fs=ceil(inv(T(2)-T(1))); The Nyquist condition is respected because you mentioned that ...
