Dear Dudes,
Urgently wanted: Is any software , able to model neumerus X per (Y1, Y2, Y3,...Yn) date values by a math. function. e.g. : X= 7.75000E-02 5.77500E-01 1.07750E+00 1.77750E+00 2.07750E+00
Y1=1.4799E-04 1.9206E-05 1.1978E-06 9.7149E-10 3.4080E-13
Y2=3.9492E-04 6.0642E-05 5.1197E-06 1.6097E-08 1.1566E-10
Y3= ... and so on.
Looking for a function (not polynomial, serie,... but a final algebraic function like: Yn=a.Ln(-b.X+c) or some final formula which can model such behviors. No matter how many coefficient this function may have. of course each Yn differs with other by some constants.
Already known that aimed eq. is not linear, and not sure if matlab could do what we want, or?
Many thanks for your notice, Looking forward to your reply,
Best regards, Bernard Luis
