Origin Ver.Origin pro 9 and Service Release (Select Help-->About Origin):
Operating System: Windows

Hi

I want to calculate the difference between two neighbouring values in the same column. Basically it is like col(A) row2 - col(A) row1, then col(A row3 - col(A) row2. Could someone help me to figure it out what to put in the command window?

Thanks!
Eicky

Just use Set Column Values and the function diff will do this, like this

Thanks! but the tricky thing is that I have 10 worksheets for one analysis, that's the reason why I prefer to use the batched command window instead of 'set column values'.

Thanks, anyway.

Thank you for the inspiration from CP, I figure it out, it should be:

---------------------------------------------
doc -ef LB
{
col(new name)=diff(col(A))};
---------------------------------------------
