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 xaxis of each plot is the sample number, and the yaxis 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(ttp) }*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 Forward Message
