MATLAB code help please

  1. MATLAB code help please....

    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 Im 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
