Not sure I understand you completely.
x= [.1,.2,.3,.4,.2,.4,.5,.6];%is there a reason why you can't make x just a row vector?
sd=.1*x;
n=sd.*randn(20,length(x))+x;%generates 20 numbers in each column corresponding to requested standard deviation and mean

Many Thank this is because x is a matrix of design points and each row represents a case so your solution is correct for just one row would you help make it valid for two rows please.
x= [ 0.1 0.2 0.3 0.4
0.2 0.4 0.5 0.6 ] ;
ist row is 0.1 0.2 0.3 0.4
2nd row is 0.2 0.4 0.5 0.6
regards

Hi
for the random normal distrbution can you help me to use seed to obtain the same result at each trail.
