Autoencoder EncoderWeights and DecoderWeights

The autoencoder takes,

autoenc=trainAutoencoder(testData,100,'MaxEpochs',50,'EncoderTransferFunction','satlin','DecoderTransferFunction','purelin');

as argument, but my question is how can I retrieve EncoderWeights, EncoderBias, DecoderWeights and DecoderBias in each epoch. Say for example, the

trainAutoencoder

will start its computation for epoch = 1, 2, 3,..., 50 so once it does for 1st epoch I want the weights to be retrieved in a matrix. How can I do this.

I tried doing this,

for i = 1:50
    autoenc = trainAutoencoder(testData,100,'MaxEpochs',i,...
        'EncoderTransferFunction','satlin',...
        'DecoderTransferFunction','purelin'); 
        EncoderWeights = autoenc.EncoderWeights
        and so and so forth...

end

but this doesn't seem to be a viable solution.

Can someone help!
