Origin Ver. 9.1 and Service Release 1(Select Help-->About Origin):
Operating System: Win 7

Is there a particular command to check, if ALL members (cells) of two datasets (colums) are equal.

e.g.:
dataset a = {1:3};
dataset b = {1:3};
c = (a==b);// (??? - expected: c = 1)
b[3] = 4; // Now a != b
c = (a==b);// (??? - expected: c = 0 but results: 1)

Also, imagine the same data put into col(a) and col(b) in a worksheet.
Can I somehow check:
d = (col(a) == col(b)) or such?

I am aware that I could script a (potential? double-) for loop look to check this line-wise, but I would like to know, if there is an easier way.

Thanks!

Hello,

You can sum the relative distance between Column A and Column B in this way:


dd=sum(Distance(0,col(A),0,col(B)));
dd=;

if value dd=0, the column A and column B should be the same.

You can refer to:

Best regards!
