Hi,
I seem to have worn the internet thin, and have scoured posts here aswell and have not found what i'm looking for. i might have misset it, if so i apologice. Also, please excuse my english.
So what i'm looking for is a way to have mathcad prime look at an equation and store coefficients as variables - maybe by comparing the equation to a "mask". please take a look at the attached file to see what i'm talking about.
Thank you in advance

Solved! Go to Solution.
If you input the equation in the right way, you can have the coefficients as a vector:
So this can be made to work with polynomials. How would you get an equation without typing it in?

You can do this (in Mathcad 11, something similar should work in Prime:
But this fails in Mathcad 11, because the coeffs symbolic instruction expects the expression to be a polynomial that is expressed in th argument of coeffs:
Maybe by combining the results it could be made to work...
Success!

Pretty cumbersome:
Then there's this:
or, reversing orders:
And this we might be able to use:
Pretty good stuff!
Wouldn't have thought of that.
I also can't think of anything else than what Luc already had shown:
[EDIT: In the meantime Fred had proved that its possible to do using a cool two step method.]
I guess it could be possible to tun those calculations into a program in Versions of Mathcad from 15 down but this sure is not possible to do in Prime as it does not allow symbolic calculations inside of a program.
Cascading also shows limitations:
but we could at least do something like
BTW, here's some kind of the reverse direction:
Oh goodness, so many answers - i see i have some stuff to experiment with. Thanks
I'll look into each answer to see which best suits my needs and get back to you.

Sorry took me some time to get back, with some fiddling i were able to make use of most of the answers. so Thank you all!
Now the dilemma is the points, since i could use most, i'm going to assign them to the first answer.
Thanx again.
