See more: Matlab
i have 3 values (28,123,56)
i need a polynomial with these values as coefficient
such that by applying any number as 'x' i should get an 8bit number

if the results of function and the values of 'x' are available (for any 3 values of x) then i must get (28,123,56)

can anyone suggest a matlab function for doing the same

We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.
Try it yourself, you may find it is not as difficult as you think!

it is not a home work it is a part of my project those 3 numbers are obtained from 6 pixels of an image my problem is when i used a function 28+123*x+56*x^2 i got some value that value is greater than 255 so i applied mod 255 but i don't know how to obtain (28,123,56) in reverse and i don't know any other polynomial that is applicable
