Normal distribution

Hi all,

I'm generating a random normal distribution and i don't control the mu and sigma (its a matlab function that i need to use because the ratio between the numbers). Is there any way to change the mu and sigma and still keep the same ratio between the numbers in the vector?

I hope you understood me,

Best regards,

No, i'm just using matlab scrip that i didn't wrote. and therefore i cant change the mu and sigma. So i want to know if i can change them and still keep the same ratio, if it possible statistically.
