MATLAB: How to create an vector contains 10000 random values that uniformly distributed with mean 1 and variance 10

how to create an vector contains 10000 random values that uniformly distributed with mean 1 and variance 10 ?

mean = 1.0;
std = sqrt(10);
N = 10000;
u = (mean-sqrt(12)/2*std) + sqrt(12)*std*rand(N,1)

u is uniformly distributed on

[a:b] = [m-sqrt(12)/2*std:m+sqrt(12)/2*std]

with the prescribed mean and standard deviation.

(mean-sqrt(12)/2*s.d.) + sqrt(12)*s.d.*rand(N,1)

is uniformly distributed on

[a:b] = [m-sqrt(12)/2*s.d.:m+sqrt(12)/2*s.d.]

with the prescribed mean and standard deviation.

Because you used a comma to define the 10000, and MATLAB sees that comma as a statement separator. MATLAB interprets this line

Impulse = 10,000*exp(-10000*t);

as two separate statements

Impulse = 10
000*exp(-10000*t);

Get rid of the comma.

Impulse = 10000*exp(-10000*t);
