Using normpdf() and a for Loop to Generate Multiple Gaussian Random Variable Arrays

1 view (last 30 days)
I would like to know how I can implement a for loop to generate multiple random values for a Gaussian distribution and then plot to a histogram. My existing code is as follows:
%%Clearing and closing all other open programs withing MatLab
close all
clc
%%Creating a matrix for the signals given
equalProbSignal = [1 0 0 0 1 0 1 1 0 0 0 1 1 1 1 0 1 0 0 1];
unEqualProbSignal = [1 1 0 0 1 1 1 1 0 1 1 0 1 1 1 0 1 1 0 1];
%%Generating a Real Gaussian Noise
X = [0.1:1:0.1];
gaussianNoise = normpdf(X);
%%Adding noise to the signal
noiseySignalEqual = equalProbSignal+gaussianNoise;
noiseySignalUnEqual = unEqualProbSignal+gaussianNoise;
%%Must repeat process for Laplacian
laplaceSignal=laprnd(1,20);
noiseySignalEqual02 = equalProbSignal+laplaceSignal;
noiseySignalUnEqual02 = unEqualProbSignal+laplaceSignal;
%%Comparing the noisey signal to the transmited one for Gaussian
gaussianNoiseEq = noiseySignalEqual;
gaussianNoiseEq > 0.5; %Finding values less than or above 0.5
result=noiseySignalEqual==equalProbSignal; %Comparing the result
figure(1);
stem(result);
GaussianNoiseUnEq = noiseySignalUnEqual;
GaussianNoiseUnEq > 0.5; %Finding values less than or above 0.5
result02=noiseySignalUnEqual==unEqualProbSignal; %Comparing the result
figure(2);
stem(result02);
%%This block will contain the same as above yet with Laplacian noise.

I have to say, I was hoping this community would of been more helpful. The lack of support doesn't really make MatLab an easy tool to learn/use. My apologies in advance for being blunt.

James, Please go to help and look for 'FOR'loop, To create random signal,again go to help and look for 'random' you will get the usefull information

HTH,
Coulda been more verbose, but here it's monday morning 0800
