buttLoop error message code lifted from Matlab example 60 Hz hum

 Using code from Remove the 60 Hz Hum from a Signal.

 

srate = input ('Enter SAMPLE RATE for this subject(check log book!):    ');   
ChannelFirst = data.ECG;
Fs=srate;
t =( 0:length(data.ECG)-1)/fs;

plot(t,data.ECG);
ylabel 'Voltage (V)', xlabel 'Time (s)'
title 'Open-Loop Voltage with 60 Hz Noise'

d = designfilt('bandstopiir','FilterOrder',2, ...
                'HalfPowerFrequency1',59,'HalfPowerFrequency2',61, ...
                'DesignMethod','butter','SampleRate',Fs);

fvtool(d,'Fs',Fs) ;           

buttLoop = filtfilt(d,openLoop);    ERROR THIS  LINE <?===========================

figure (2);
plot(t,data.ECG,t,buttLoop);
 ylabel 'Voltage (V)', xlabel 'Time (s)';
 title 'Open-Loop Voltage', legend('Unfiltered','Filtered');

    [popen,fopen] = periodogram(data.ECG,[],[],Fs);
   [pbutt,fbutt] = periodogram(buttLoop,[],[],Fs);

You can use get command to get all possible properties applicable on axes.  I am putting some code for better understanding. Just run this code in MATLAB to get the necessary details. clc clear close all theta=0:pi/20:2*pi; y=sin(theta); plot(theta,y,'r','linewidth',2) xlabel('\theta') ylabel('sin(\theta)') get(gca) set(gca,'color','red')

How to run .m file in python?

  I have a .m code what I want to run in python. Is it any easy way? 1. this code is not a function. 2. don't want to show the matlab window. NOTE:- Matlabsolutions.com  provide latest  MatLab Homework Help, MatLab Assignment Help  ,  Finance Assignment Help  for students, engineers and researchers in Multiple Branches like ECE, EEE, CSE, Mechanical, Civil with 100% output.Matlab Code for B.E, B.Tech,M.E,M.Tech, Ph.D. Scholars with 100% privacy guaranteed. Get MATLAB projects with source code for your learning and research. T his is not a big deal. The python code looks like: import matlab.engine eng = matlab.engine.start_matlab() eng.simple_script(nargout=0) eng.quit() The Matlab script would be perhaps this one line saved as simple_script.m: a = 'it works easily...' Make sure that the script is saved in a folder matlab knows as a search folder. Then run your python script and get the answer:   SEE COMPLETE ANSWER CLICK THE LINK https://www.matlabsolu...
