How do I create a random matrix from a normal distribution given the mean and variance (mean = 2 and variance = 8).

From a 100x100 random matrix that I have previously created I need to create another random matrix from a normal distribution given the mean and variance (let's say that mean is 2 and variance is 8). Does anyone know how to do this?

Thank you Tai, really cool.

[Tai Lopez]

sorry, what do you mean by this, Luis?

Just my way of saying thank you for all your videos on how to make money, I now own a grand total of 5 garages.

[Tai Lopez]

Amazing! I'm glad that you're happy now. Is that where you filmed your Despacito?

@Tai, @Luis —

I do not have any MATLAB garages. What am I doing wrong?

I would just do this:

mu = 2;
vr = 8;
RandomNormalMatrix = mu + sqrt(vr)*randn(100);

See the documentation on the randn (link) function for details.

I understand now, thanks!

As always, my pleasure!

Could you tell me how the result changes if we use randn(1000000) in spite of randn(100)?

Thank you,
