generate n random number between two numbers follow exponential distribution

I need to generate n random number between a and b which follow the exponential distribution (In this perticular case a=0, b=75, random number =t=occurance time; I need exactly "n=60" random numbers of "t" which are less than 75). here is what I have done:

mu=475; % return period

lambda=1/mu; % occurance rate

u=rand(100,1); % uniform random numbers between 0 and 1

t=icdf('Exponential',u,mu); % exponential random numbers of time

I would use the Statistics and Machine Learning Toolbox exprnd (link) function.

Experiment to get the result you want.

Thanks for the response. If doing so, how I can generate ''n'' random numbers between "a" and "b" ?

[Star Strider]

My pleasure.

Try this:

mu = 475;
n = 1E+5;
R = exprnd(mu,1,n);
a = 10;
b = 20;
Rbounded = R((R>=a) & (R<=b));
n = 42;
R_return = Rbounded(randperm(numel(Rbounded),n));

That will give you ‘n’ values from the exponential distribution with .

Experiment to get the result you want.

With Cupid the command is

somerands = TruncatedX(Exponential(lambda),a,b).Random(n,1);
