Hi,
I defined a function giving a set of points with linearinterpol then I added
another function, which I defined with a simple formula. The resulting
function is still strictly rising in value, so mathematically it can be
inverted, so I wanted to invert the function, but I could not find an
operator for that anywere, I tried
simplify([y=f(x)],x), which produced some expression, but not what I needed
and funcsimplify([y=f(x(y)),x(y)), which failed (division by zero).
Is there a standard way to do this ? it seems something pretty basic.
for any help I would be very grateful,
Stefan
