Access to the variable "e" in the +mse folder?

For a neural network I want to write my own Performance function. As a template I use the MSE Mean squared error performance function. In the Folder +mse are several functions:

• apply.m
• backprop.m
• dperf_dwb.m
• forwardprop.m
• name.m
• normalize.m
• parameterInfo.m
• perfw_to_ew.m
• perfwb.m
• type.m

The apply.m function looks like this:

function perfs = apply(t,y,e,param)

    perfs = e .* e;

end

Where can I get access to the variable e? Respectively modify or define it to my own purposes? I can't find the directory where e is deposited/calculated.

Thanks in Advance

Hi David,

The easiest way to write your own performance function is to use the files from 'mse' which you are correctly doing and change the functions in the +mse folder, such as the 'apply' function to the performance function you wish to use. Is there a reason why this is not possible in your case?
