I was amazed when use randn command at Matlab. randn command will generate random data every we call that command. After I search at google, I found how to make this happen. I get this code at seismic unix source code. This code will generate random noise or white noise with Gaussian ...
% GAUSSIAN WIDTH (in pixels) sig = 2; % GENERATE SMOOTH NOISE X = rands(sz,sig); % CALCULATE CENTER INDICES Nx0 = ceil(size(X,1)/2); Ny0 = ceil(size(X,2)/2); Nz0 = ceil(size(X,3)/2); % VISUALIZE SMOOTH NOISE

It also explores statistical properties of additive white Gaussian noise (AWGN). The chapter provides step-by-step code exercises and instructions to implement execution sequences. The MATLAB command randn(1,b) generates a 1驴驴b vector whose elements are realizations of independent and identically ...
MATLAB Online에서 열기 If i understood you correctly, you want to get the same random values every time you run your code. This is reached by the rng function. 테마복사 rand(1,10) ans = 0.4387 0.3816 0.7655 0.7952 0.1869 0.4898 0.4456 0.6463 0.7094 0.7547 s = rng...
You cannot remove the seed option, but you can use a random seed. For example:
Noise (arrow) causes the percept to change more quickly when the boundary between the two wells is low. (b) Experimental outline. In Experiment 1 noise (zero-mean Gaussian random noise) was applied to the visual stimulus for 5 seconds followed by 5.5–7 seconds of no stimulation. ...

I am using a gaussian noise generator from Simulink to generate the random numbers using a single random seed. The simulation is running to inf., so that I could get random numbers upto atleast 1E+16 random numbers. If I am using a Mersenne twister...
Simulink / Sources Description TheRandom Numberblock generates normally distributed random numbers. To generate uniformly distributed random numbers, use theUniform Random Numberblock. Both blocks use the Normal (Gaussian) random number generator ('v4': legacy MATLAB®4.0 generator of therngfunction). ...
