Hi, all.
I want to calculate the abscissa values for the given vertical values.

For example,
x = findgen(1000)/1000*4*pi
y = cos(x)
I want to get the abscissa values for y=0.
For this example, the results shoule be [!pi/2, 3*!pi/2, 5*!pi/2, 7*!
pi/2].
But how can I get it by IDL codes?

Best wishes,
jdu
