layers = [
imageInputLayer([28 28 1],'Name','input')
convolution2dLayer(5,20,'Name','conv_1')
reluLayer('Name','relu_1')
additionLayer(2,'Name','add')
fullyConnectedLayer(10,'Name','fc')
softmaxLayer('Name','softmax')
classificationLayer('Name','classoutput')];
lgraph = layerGraph(layers);
lgraph = connectLayers(lgraph,'input','add/in2');
>> larray = [batchNormalizationLayer('Name','BN1')
leakyReluLayer('Name','leakyRelu_1','Scale',.02)];
newlgraph = replaceLayer(lgraph,'relu_1',larray);
Undefined function or variable 'replaceLayer'.
Why in some computers works and in other it does not works and they are the same version with the same toolboxes??

Undefined function or variable 'replaceLayer'.
Error in training (line 22)
Layer_Graph = replaceLayer(Layer_Graph, Feature_Learner.Name, New_Feature_Learner);
how can solve this problem??

Add following lines:
Layer_Graph = layerGraph(Layer_Graph);
Layer_Graph = replaceLayer(Layer_Graph, Feature_Learner.Name, New_Feature_Learner);

The 'replaceLayer' function is not a standalone m function. It is a class method of 'layerGraph' class.
Since it is a class method, it is defined in the class file for 'layerGraph' and can be used only with particular layers.
For more information, please refer the 'Objective Functions' of 'layerGraph' at the documentation link mentioned below:
