for neural network training i want to know which transfer function which is the best? trainlm ,or trainbr and why (if possible) ??

They are training functions, not transfer functions

tansig, purelin and softmax are transfer functions.

Always use the default. There is no need to specify. See the documentation for an alternative only if you are having a problem caused by this choice.

For regression and curvefitting,

 help fitnet
 doc fitnet
 help trainlm
 doc trainlm

For tiny data sets trainbr works better

For huge data sets trainrp and trainscg work better

For classification and pattern recognition

 help patternnet
 doc patternnet
 help trainscg
 doc trainscg

Hope this helps.

Thank you for formally accepting my answer
