how can i make this layers?

</matlabcentral/answers/uploaded_files/127973/%EC%BA%A1%EC%B2%98.PNG> how can i make this arrays?

especially i can't figure out how to get the skip convolution part,

i made like this:

clc; clear;

Downsampling_blk = [

batchNormalizationLayer('Name','batchnorm_1')

reluLayer('Name','relu_1')

convolution2dLayer(3, 32, 'Stride', 2, 'Name','conv_1')

batchNormalizationLayer('Name','batchnorm_2')

reluLayer('Name','relu_2')

convolution2dLayer(3, 32, 'Stride', 1, 'Name','conv_2')

additionLayer(2,'Name','add');

];

skipConv = convolution2dLayer(3, 32,'Stride', 2,'Name','skipConv');

%skipConv = convolution2dLayer(3, 32,'Stride', 2,'Name','skipConv');

lgraph = layerGraph(Downsampling_blk); lgraph = addLayers(lgraph,skipConv);

lgraph = connectLayers(lgraph,'skipConv','add');

figure plot(lgraph)
