Simulink model for Fetal ECG extraction (HDL Compatible algorithm)

This is an HDL Coder compatible Fetal ECG extraction algorithm.

Editor's Note: This file was selected as MATLAB Central Pick of the Week

This is an HDL Coder compatible Fetal ECG extraction algorithm. The Simulink model follows the floating point MATLAB algorithm with some changes forced by the HDL Coder compatibility.

The "blue" subsystem is HDL Coder compatible.

* Note: this is only a demonstration of tools' capabilities and not a commercial grade algorithm!

for i = 1:14

x(m+1) = a(i) + slope * (m - d(i));
end

Hello, I can't run the proyect, "Undefined function 'ecg' for input arguments of type 'double'". Can you help me? Thanks.
PD: The code is amazing

Shrishail Ganiger

what is Hd means in the code??

Great job!
PS: Dear Dr. Igal Sebag, I'd like to use this code for modifications, doing experiments and then contribute to a book chapter, may I know which publication from you should I cite? THanks very much!

Best regards,

Xin
