SUMMARY

This discussion centers on seeking assistance with MATLAB programming, specifically for reducing noise in audio communication using Hamming codes. User Jennifer, a beginner, requests help in understanding her sample code and the associated plots, which represent sound waveforms. Another user, Warren, seeks guidance on solving a complex partial differential equation (PDE) related to thermal properties in MATLAB. Both users emphasize the urgency of their requests due to impending deadlines.

PREREQUISITES
  • Basic understanding of MATLAB programming
  • Familiarity with Hamming codes for error correction
  • Knowledge of plotting functions in MATLAB
  • Understanding of partial differential equations (PDEs)
NEXT STEPS
  • Explore MATLAB's built-in functions for plotting and interpreting sound waveforms
  • Learn about Hamming codes and their implementation in MATLAB
  • Study MATLAB's PDE toolbox for solving complex equations
  • Review MATLAB tutorials focused on audio signal processing
USEFUL FOR

This discussion is beneficial for beginner MATLAB programmers, audio engineers working on noise reduction, and researchers dealing with thermal properties in materials using MATLAB.

MATLAB code help please...

Hi,
My name is Jennifer.Iam new to Matlab programming.Iam working on reducing the noise content in audio communication.Iam using Hamning codes for the same.I have a sample code with me,which iam uploading in a zip file.Iam unable to understand how it works.Can someone please explain me how the code is written,what it means and what the different plots mean and how to read them? I have trouble especially with the plots trying to understand them.

Being a beginner,Iam having a lot of trouble trying to understand.Iam trying to read Matlab tutorials at the same time but I have to finish up this work soon before the deadline.So can anyone be kind enough to help me through this please? I would greatly appreciate all the help I receive. Thank you in advance.

The plots appear to be sound waveforms. The x-axis of each plot is the sample number, and the y-axis is the value of each sample.

Hi i Would like to solve the the following eqn using Matlab

Since I am new to Matlab, I would request u to help me in this regard
(∂^2 T)/〖∂r〗^2 + 1/r (∂T )/∂r+(∂^2 T)/〖∂z〗^2 = 1/α (∂T )/∂t+τ/α (∂^2 T)/〖∂t〗^2 - { (1+δ(t) )-(1+δ(t-tp) }*IoKa/k 〖exp( - 2r/σ^2 〗_^2)exp(-zka)

where δ(t) =76ns

Δz = 0.- 2.5
Δz = 2.5 - 50
Δr = 4

If Δz = 0.- 2.5, I have to use thermal properties of my material

if Δz = 2.5 - 50, I have to use thermal properties of glass.

Could u help me in this regards
