How can I find the intersection between two interpolation functions?
data1 = Table[10*x, {x, 0, 10, 1}]
data2 = Table[-10*x, {x, -10, 2, 1}]
intdata1 = Interpolation[data1];
intdata2 = Interpolation[data2];
ListLinePlot[{data1, data2}]
Solve[intdata1[x] == intdata2[x], x]
This doesn't work, with an error of
Solve::nsmet: This system cannot be solved with the methods available to Solve.
