Hi all does the training function affect on the run data? I compared the result between two different functions (trainrp, trainlm). the obtained results are different. the accuracy resulted by trainlm is much better than trainrp (i.e. r value) but the concept behind the studied role appeared by trainrp is used!
thank you for help in advance.

Before asking questions about any functions it is good practice to first use the MATLAB info via, e.g.,
help trainrp
doc trainrp
type trainrp
You will find reference to the terms
resilient backpropagation algorithm and RPROP
which can be used in GOOGLE and WIKIPEDIA
Hope this helps.
Thank you for formally accepting my answer

I don't know. In 36 years of designing NNs, I don't believe I ever used trainrp.
