hello frnds, I have a doubt about selecting random no generating capacity of matlab. Can any one suggest me using random no generator in order to randomly select an element from a the elements of the given array? for eg if the array is AR=[1,2, 3, 4 , 6] then the random number generator should be able to select any element from the AR randomly

Hi everybody; I want to learn about if it is possible rearrange a vector in MATLAB in a random manner. For example i have the vector=[1 3 5 8 7 0] and i want a new vector using the vector elements but different order i.e. new_vector=[0 7 3 1 8 5 ]; this order sould be random. Any idea? I think to use "randint" to regenerate indexes then create new vector using new index order. But problem is...

hi, u can use 'rand' function in Matlab which gives the uniform random in the range (0,1). if u want Random numbers in (-1,1) use 2*rand(1,20)-1 so for (-100,100) 100*(2*rand(1,20)-1); hope it will helps u. if u aren't intrested to use 'rand' fun

Hi, All: Do you know how should I generate the Random Vectors given the Covariance Matrix? Or in general, how should I realize the correlation between Random variables? eg: X=[x1,x2] Covariance Matrix is[1,0.5;0.5,1] I want to generate 10

Dear all, I am working on trying to simulate a random signal of a given frequency range (say between 0 and 5000 Hz) in MATLAB. I have used signal generator apparatus in which I just select the kind of signal output (Sine or Random) and choose a frequency range. If I was to simulate the above in MATLAB, how could I do it? I would be really grateful for any help on this. Merry Christm...

Hi, I am an Mechanical student and i am trying to generate a random rough surface (with specified ACF and Std Deviation) using 2D FIR filter in Matlab. I come across a paper that helps me doing that. For that, first i need to generate a input sequence composed of independent random numbers {?(I,J)}. The paper says its PSD must be a constant. I used matlab to generate independent r...

Hi, I got a program as below which generates random binary codes (Phase 1.1). After that have to add parity bit to the codes(1.2). The next step is to generate error to the code, but it generates error ( Index exceeds matrix dimensions). Y is it so and some one got the right answer? %Phase 1.1 n=10;% # of bits b=round(rand(1,n));% creates random binary code disp('Random Da...

Hello everybody, first of all I would like to apologize if what I'm asking is terribly obvious or if what I'm saying is completely wrong. I'm quite new at discrete signal processing! Probably it will sound quite strange to most of you since it isn't something which usually occurs in practical situations, but I need to get samples of a random s

Dear All, my project requires me to generate random samples which follow a Hyper- Erlang distribution. How can i do this in Matlab? In my case, the Hyper-Erlang distribution consists of weighted sum of 2 erlang distributions. (very much the same as hyper exponential distirbution, which is made up of weighted sum of exponentials) Matlab is able to generate random samples from some commo...
