Hi,
I want to do a simple test with an if-function (to binarize a signal).
Col(A): (signal Y, sampling intervall dx=0,001)
Col(B): (values Y, sampling intervall dx=1)
If the value in Col(A) is smaller than the value of the matching sampling intervall in Col(B)--> 1, else --> 0.
How can I realize that in a very simple way, maybe with "set column values" I've never worked with LabTalk yet. (I have OriginPro)
Thanks for each help!

Hello,
Origin supports conditional operator. The syntax is
Expression1 ? Expression2 : expression3
If expression 1 is true, then run expression2. If false, then use expression 3.
E.g. if you have col(A) and col(B) with values, add a new column C.
Set column C's values to be
Col(A)<col(B)? 1 : 0
I am not sure what you mean by "If the value in Col(A) is smaller than the value of the matching sampling intervall in Col(B)", but u can see the example above to get an idea.
Thanks, Snow Li
