How to perform cumulative product on a discrete signal in Matlab

I tried to perform cumulative product on a discrete signal. But it keeps throwing errors. Am not sure how to go about it.

Here's my code:

function [i_o,q_o] = Accumulate(I, Q)

cumprod = dsp.CumulativeProduct;

i_o = cumprod(I);

q_o = cumprod(Q);

Thanks

clear cumprod

What is the full and exact text of the error messages you receive when you run your code? Show us all the text displayed in red in the Command Window when you run your Accumulate function.

Hi Steven,

I get the followinge error:

Error using Accumulate (line 13)

Not enough input arguments.

Line 13 is this line: i_o = cumprod(I);

How did you call the function? I assume you didn't pass input arguments

It must be called with input arguments, like

% 
% Code to find (or) define I, Q
%
[i_o,q_o] = Accumulate(I, Q); % Call the function with input arguments
%
% Code using i_o, q_o
% 

function [i_o,q_o] = Accumulate(I, Q)
cumprod = dsp.CumulativeProduct;
i_o = cumprod(I);
q_o = cumprod(Q);
end
