How can I find a multiplication coefficient between two signal?

Hello!! I have two signals measured experimentally. Theoritically, the second signal can be obtained with the first one by multiplying it with a constant ( this constant characterize my system). How can I find on matlab this constant. I tried "corr" but it doesn't work. Thank you so much for your help!!!

Your need is to solve the problem

signal2 = constant*signal1

Where the variable "constant" is unknown. This is easy to solve in MATLAB.

constant = signal1(:)\signal2(:);

Thank you for your answer.

Actually, the two signals are mesured experimentally and have noise and incertitude, that's why i can't do a simple ratio. But I did the root mean square error and it works.
