Trouble with function using variable inputs.

Hello, I am fairly new to Matlab and am having a little difficulty using the "varargin" statement.
I am trying to create a function which multiplies matrices in a specific way.
The number of inputs will always be some multiple of 3 PLUS 1 (i.e. 4,7,10,13...). Taking as an example an input of 4 variables, (a,b,c,d), I want to do the following operation:
M = [1 0;-1/a 1]*[1 b/c;0 1]*[1 0;-1/d 1];
Putting this into a loop, I would have something like:
M = [1 0;-1/a 1];
N = length(varargin); %number of input variables
for k = 2:3:N
b = varargin(k);
c = varargin(k+1);
d = varargin(k+2);
M = M*[1 b/c;0 1]*[1 0;-1/d 1];
end
However, this does not work. I believe it has to do with the fact that the input variables are not doubles. Does anyone have an advice for me?
Please let me know if I was too vague in my description.
Thanks!

Do you want to do a matrix multiplication or an element-by-element multiplication?
