return coef. for best fit of 4 points

[JBlackhole]

To all,

See attached mcad sheet

Given the set of 4 points is there a way of returning the coefficient C0 and m of equation y(x)=C0x^m for a best fit?

Thanks

Regards

Not sure if its the best way, but heres one way to do it.

You may also use a solve block with minerr which may give you more flexibillity.
