"Error using perceptron Too many output arguments. "

I have this simple code copied from matlab:

P = [0 2];

T = [0 1];

net = perceptron;

net = configure(net,P,T);

However, I get the following error:

Error using perceptron

Too many output arguments.

Any help will be highly appreciated..

Which line throws the error? net = perceptron; or net = configure(net,P,T);?

I am assuming that you are using MATLAB R2019a. Try running the following script on MATLAB command window:

>> which perceptron

This command determines which function script is being called along with the path of the file. You should get the following output. Here, matlabroot is the location where MATLAB is installed.

matlabroot\toolbox\nnet\nnet\nnnetwork\perceptron.m

If your output is different from the above, it means that there are file(s) named 'perceptron.m' on your path which is/are overriding the inbuilt function. Try renaming/removing those file(s) and run the code again. This should run fine.

Refer to the following documentation link to get insights on how MATLAB determines the function precedence order.

Hope this helps.
