trying to follow the convert-to-spiking example. load("DigitsDataTrain") does not work. I can't find a DOWNLOAD for this .mat file either. John

I'm trying to follow the convert-to-spiking NN example.

https://www.mathworks.com/help/deeplearning/ug/convert-to-spiking-neural-network.html

>> load("DigitsDataTrain")

Error using load

Unable to find file or directory 'DigitsDataTrain'.

*** There is nowhere to download this .mat file that I can find. Thanks, John

Open the example in MATLAB or in MATLAB Online. This will cause the current directory to change to the directory containing the example and its helper files, one of which is that MAT-file.

Hi thanks for the feedback,

You suggest "Open the example"... huh? .... (apologies), I tried this on my matlab command line. Errors result. I tried Matlab Online no progress there either. *** I'd like to be able to load the "DigitsDataTrain" file. ***

>> openExample('nnet/ConvertConvolutionalNetworkToSpikingNeuralNetworkExample')

Error using findExample

Unable to find "nnet/ConvertConvolutionalNetworkToSpikingNeuralNetworkExample". Check the example name and try again.

Error in setupExample (line 6)

metadata = findExample(arg);

Error in openExample (line 30)

[workDir,metadata] = setupExample(exampleId, workDir);

Matlab online: I selected "Try this example"

[John Hobbs]

I generally

[1] load the data.

[2] look at the data

[3] operate on the data... I can't get past [1].

V/r,

John Hobbs

Do you have Deep Learning Toolbox installed? This example is part of this product so you will need it to load the MAT-file (and to run the commands later in the example.) You can check using the ver function.

Which release are you using? ver will also show this information.

That example needs R2023b or later.
