How do I write a function that performs moving average using data from a text file? The equation I have to use is mentioned in the body and i do not understand what function to create.

Write a function that performs the moving average, equation (2), of any 1- dimensional input data for any non-zero and positive order M. Be sure to add M −1 zeros at the beginning of the data so that your output data will be the same length as your input data.

y[n] = 1/M Σx[n − k]

lower limit k= 0 upper limit M −1
