Question
In the deep learning toolbox, I cannot easily manipulate a specific layer. For example, I know the name of a layer. How can I quickly find it in the layer array?     layers = [convolution2dLayer(3,3,'name','aa'); reluLayer('name','bb'); convolution2dLayer(3,3,'name','cc')] For example, if I want to find a convolutional layer named "cc", can I only find one by one in a for loop? When there are many layers(There are dozens of layers), this method is very inefficient!     for i = 1:length(layers) if strcmp(layers(i).Name,'cc') myfindLayer = layers(i); break; end end If only myfindLayer = layers ('cc') can be operated like this! I hope the official will consider such a method, easy to operate!

I understand that you wish to search a layer based upon its name and not using its index. You can make use of the Name property of a layer. Let’s consider the layer array you mentioned in the question and you want to find the layer with name cc.
 
You can use –
 
layers({layers.Name} == "cc") 

or

layers(strcmp({layers.Name}, 'cc')) 

Don’t forget to put double-quotes (“ “) in case you are comparing using ‘==’ operator or else use string(‘cc’).
