Hello I have written a code that performs newton interpolation. After I determined the coefficients I want to display the simplified expression like this: p(x) = p14*x^14 + p13*x^13 + … + p0
But when I use the collect function it displays the result as follows:
((1613572414787747*13^(1/2)*17^(1/2))/1667355148462087077893881565539536391777188164935759167488 + (1613572414787747*22^(1/2))/2157753721539171512568552614227635330535184684034511863808 + 3914999446024239438846407105870793530675/11373727500204176163375146989836406690440670303259304015465585573888)*X^14 + ...
I would like to display 3.4421e-28*X^14 + …
How do I do that?
This is the code I used to create formula out of th calculated cofficients:
%display the formula (collect or factor function)
syms X;p_x = collect( a(1)... + a(2)*(X-x(1))... + a(3)*(X-x(1))*(X-x(2))... + a(4)*(X-x(1))*(X-x(2))*(X-x(3))... + a(5)*(X-x(1))*(X-x(2))*(X-x(3))*(X-x(4))... + a(6)*(X-x(1))*(X-x(2))*(X-x(3))*(X-x(4))*(X-x(5))... + a(7)*(X-x(1))*(X-x(2))*(X-x(3))*(X-x(4))*(X-x(5))*(X-x(6))... + a(8)*(X-x(1))*(X-x(2))*(X-x(3))*(X-x(4))*(X-x(5))*(X-x(6))*(X-x(7))... + a(9)*(X-x(1))*(X-x(2))*(X-x(3))*(X-x(4))*(X-x(5))*(X-x(6))*(X-x(7))*(X-x(8))... + a(10)*(X-x(1))*(X-x(2))*(X-x(3))*(X-x(4))*(X-x(5))*(X-x(6))*(X-x(7))*(X-x(8))*(X-x(9))... + a(11)*(X-x(1))*(X-x(2))*(X-x(3))*(X-x(4))*(X-x(5))*(X-x(6))*(X-x(7))*(X-x(8))*(X-x(9))*(X-x(10))... + a(12)*(X-x(1))*(X-x(2))*(X-x(3))*(X-x(4))*(X-x(5))*(X-x(6))*(X-x(7))*(X-x(8))*(X-x(9))*(X-x(10))*(X-x(11))... + a(13)*(X-x(1))*(X-x(2))*(X-x(3))*(X-x(4))*(X-x(5))*(X-x(6))*(X-x(7))*(X-x(8))*(X-x(9))*(X-x(10))*(X-x(11))*(X-x(12))... + a(14)*(X-x(1))*(X-x(2))*(X-x(3))*(X-x(4))*(X-x(5))*(X-x(6))*(X-x(7))*(X-x(8))*(X-x(9))*(X-x(10))*(X-x(11))*(X-x(12))*(X-x(13))... + a(15)*(X-x(1))*(X-x(2))*(X-x(3))*(X-x(4))*(X-x(5))*(X-x(6))*(X-x(7))*(X-x(8))*(X-x(9))*(X-x(10))*(X-x(11))*(X-x(12))*(X-x(13))*(X-x(14))... + a(16)*(X-x(1))*(X-x(2))*(X-x(3))*(X-x(4))*(X-x(5))*(X-x(6))*(X-x(7))*(X-x(8))*(X-x(9))*(X-x(10))*(X-x(11))*(X-x(12))*(X-x(13))*(X-x(14))*(X-x(15))..., X )
Thanks in advance!
