Multiply value with value in previous position in Matlab cell

Hi,

I would like to create an equation using for loop for multiply current values with previous position but my code does not work. Please give some guideline for me. I attached my code (data_test01.m) and excel data (data.xls). The formula in excel is example that is the same thing I want to do in matlab.

The problem is that in this expression

Phi_wp(n,:)

n=0 the first time through the loop, and the elements Phi_wp(0,:) do not exist, because MATLAB has 1-based indexing.

This is a common situation. Typically you just have to handle that first case before the loop, and then start your loop from m = 2.

Thank so much.

I tried that but it seems like the answer is not correct comparing to the value in last attached excel file.
