How do I format an input (X) to the trainAutoencoder function. I tried making a 2D matrice as told on its documentation but get the following error: "Undefined function 'trainAutoencoder' for input arguments of type 'double'. " traindata is my X input which is a 3 X 5 double as shown in the Workspace
%Make Training data traindata = [5,5,5,1,5; 5,5,5,1,5; 5,5,5,1,5];
rng('default') hiddenSize1 = 3; autoenc1 = trainAutoencoder(traindata ,hiddenSize1, ... 'MaxEpochs',400, ... 'L2WeightRegularization',0.004, ... 'SparsityRegularization',4, ... 'SparsityProportion',0.15, ... 'ScaleData', false);

trainAutoencoder is a function built in matlab2015b that use neural network toolbox version 9.0, so it is not defined on matlab2015a or other previous versions. try to upgrade your toolbox and you will find the function.
