Can you help us debug and fix this code entirely?
You can get nearspeech.mat and farspeech.mat as part of the example openExample('audio/AcousticEchoCancellationAecExample')

Let us take an example: finding the row indices of the first non-zero row in a 2D matrix. A = full(sprand(10000,500,0.1)); Loo...

The problem is that when I use vpa(U(x,t), 7) to get the solution with 7-digit decimal precision, MATLAB still outputs a very long and complicated expression. how do I fix it?
Observe: a1 = vpa(sym(pi), 7) a2 = vpa(a1, 10) a3 = vpa(a2, 15) a4 = a3 - pi double(a4) From this we deduce that vpa() co...

I cannot find R2023a installer. In the drop-down, there is only R2024b.
That can happen if you do not have a MATLAB license registered against your MATLAB Central account.
