Homework Help: Muon lifetime experiment

  1. Apr 27, 2010 #1
    1. The problem statement, all variables and given/known data
    As a lab experiment, we must try to measure and calculate the lifetime (τ) of a muon. After all data is collected, the lifetime can be calculate by using the maximum likelihood estimation.
    The function on which MLE is applied:

    One of the goals of this experiments is to do the MLE manually. For that I solved al the equations that are given by the definition of MLE. I finally ended with this equation:

    Ta, Tb and N are constants, Ti is the dataset and Tau is the lifetime (this should be calculated).
    I know this equation is correct. It should now be solved with mathematical software (I prefer matlab).

    2. Relevant equations
    My problem is to solve this in matlab. When i try to do this, it gives me the error:
    "The expression to the left of the equals sign is not a valid target for an assignment."

    3. The attempt at a solution
    This is the code i used:
    Ti is a variable with 61565 rows and one column

    Does anyone know what im doing wrong?
