I have the following basis, (fllngpwr}, and expression, {exp3}:
fllngpwr={1,\[Alpha]^UnderBar[1], \[Alpha]^UnderBar[2],\[Alpha]^UnderBar[3]}
exp3 = 3 - \[Alpha]^UnderBar[1] + 2\[Alpha]^UnderBar[2] + 5\[Alpha]^UnderBar[3]
I would like to extract the coordinates of the expression {exp3} in terms of the basis {fllngpwr} using:
cordvect =ResourceFunction[CoordinateVector[{exp3},basis,{\[Alpha]}]]
I must have something wrong since it seems to evaluate, by that I mean it fills in the exp3, basis and alpha. For example:
ResourceFunction[CoordinateVector[expression,basis, alpha]]
Any suggestions would be welcomed.
Thanks.
