Using Cell Arrays to Store a Matrix Each Time Through a Loop

I'm looking to store the value "p" (3x1 matrix) found each time going through a loop. In my code below, I attempt to use a cell array through the line "M{i}=p" where i is the value increasing by 1 each time I go through the loop. What I'm finding is that the cell is made, but instead of putting the second loop in the second cell, it just overwrites p in the same first cell. I appreciate any help in fixing this!

Thanks,

You have multiple iterations using an iterator i ... I suggest to use more descriptive variable names :D

THANK YOU SO MUCH! Being totally honest, this code is a combination of a bunch of little things I've written and stuff I've found on the internet. I didn't even notice i was redefined later in the code.
