disconnectLayers

Disconnect layers in layer graph

Syntax

newlgraph = disconnectLayers(lgraph,s,d)

Description

newlgraph = disconnectLayers(lgraph,s,d) disconnects the source layer s from the destination layer d in the layer graph lgraph. The new layer graph, newlgraph, contains the same layers as lgraph, but excludes the connection between s and d.

Examples

Disconnect Layers in Layer Graph

Create a layer graph from an array of layers.

layers = [
    imageInputLayer([28 28 1],'Name','input')  
    convolution2dLayer(3,16,'Padding','same','Name','conv_1')
    batchNormalizationLayer('Name','BN_1')
    reluLayer('Name','relu_1')];

lgraph = layerGraph(layers);
figure
plot(lgraph)

Disconnect the 'conv_1' layer from the 'BN_1' layer.

lgraph = disconnectLayers(lgraph,'conv_1','BN_1');
figure
plot(lgraph)

Input Arguments

lgraph — Layer graph

LayerGraph object

Layer graph, specified as a LayerGraph object. To create a layer graph, use layerGraph.

s — Connection source

character vector | string scalar

Connection source, specified as a character vector or a string scalar.

• If the source layer has a single output, then s is the name of the layer.

• If the source layer has multiple outputs, then s is the layer name followed by the character / and the name of the layer output: 'layerName/outputName'.

Example: 'conv1'

Example: 'mpool/indices'

d — Connection destination

character vector | string scalar

Connection destination, specified as a character vector or a string scalar.

• If the destination layer has a single input, then d is the name of the layer.

• If the destination layer has multiple inputs, then d is the layer name followed by the character / and the name of the layer input: 'layerName/inputName'.

Example: 'fc'

Example: 'addlayer1/in2'

Output Arguments

newlgraph — Output layer graph

LayerGraph object

Output layer graph, returned as a LayerGraph object.
