I have some questions about the example "Denoise Signals with Generative Adversarial Networks"

when i run the example, I get the following errors

1. The function or variable 'helperDeepSignalDenoiserAE' is not recognized.

Error denoise (line 15)

helperDeepSignalDenoiserAE(SignalLength=1024, ...

corresponds to this part of the program

2. The function or variable 'helperDeepSignalDenoiserGAN' is not recognized.

Error denoise (line 38)

helperDeepSignalDenoiserGAN(SignalLength=1024, ...

corresponds to this part of the program

if you have some methods to solve that, please tell me, thank you very much, have a nice day!

When you

openExample('deeplearning_shared/DeepSignalDenoiserExample')

then the directory that you are automatically cd()'d to includes the files helperDeepSignalDenoiserGAN.m helperDeepSignalDenoiserAE.m

Thank you very much! i have obtained the helperDeepSignalDenoiserAE and helperDeepSignalDenoiserGAN, but when i run the program, I get some errors again. Do you know how to solve these problems, have a nice day！

error:

Incorrect use of eval

The function or variable 'transposedConv1dLayer' is not recognized.

Error helperDeepSignalDenoiserAE/initializeDenoisingAutoencoder (line 281)

eval("tconv_"+ii+"=transposedConv1dLayer("+this. FilterSize+","+NumFilters(ii)+",'Stride',2,'Cropping','same','Name','tconv_"+ii+"'); ");

Error helperDeepSignalDenoiserAE (line 58)

this.initializeDenoisingAutoencoder();

Error denoise (line 15)

helperDeepSignalDenoiserAE(SignalLength=1024, ...

[Walter Roberson]

transposedConv1dLayer is a function that is part of Deep Learning Toolbox. It was introduced in R2022a. Is it possible that you are using an older MATLAB release?

[Yi Ma]

Yes, thanks for your answer. It is indeed the issue caused by the version of MATLAB. Have a great day！

The helper functions are at the bottom of the page-

thank you for your answer, but i don't find the function which have the name of "helperDeepSignalDenoiserAE" or "helperDeepSignalDenoiserGAN"

At the bottom of the page, there are only these functions below：
