How to transform fully connected layer into convolution layer?

I want to replace a fully connected layer with a convolution layer, but I don't know how to complete it. I reference help document, and find a function named "transposedConv2dLayer", but I don't believe "cropping" is helpful. So if somebody could give me any suggest, thanks a lot.

Hello QU,

Can you please tell me if you're using a Series or DAG network? The steps to replace a layer is different for these 2 network types.

For a Series Network, follow steps here --> https://www.mathworks.com/help/nnet/examples/transfer-learning-using-alexnet.html#d119e3782

For DAG follow this --> https://www.mathworks.com/help/nnet/ref/nnet.cnn.layergraph.html?s_tid=doc_ta#d119e84822

 Also, is the motivation behind replacing the FC layer with a conv2d is to make the network deeper?
