Hello everyone! Can anybody help me?
I need to create y=A(exp(B*x)-1) fitting function, where A and B will be automatched parameters(sorry, my english isn't very good, maybe it is called autosorted parameters). help me plz as soon as possible! |

I mean I need these parameters to be autocalculated. for example I have initial value for B=39.4 and i need parameter A to be counted by origin to fit my experimental points |

I don't know what you mean by automatched or autosorted, but you should be able to define this well-behaved function with just about any initial values you like and it should fit. Possibly you need constraints on the parameters? You could enable constraints and use something like
A > 2 * B
or
A < B |
