I think it can't be a solution bcause the number of column is a variable :question:

Hallo, I have this problem, I take measure from a machine giving the following input: star vol, stop volt, step size, number of points. What i recive from the machine are two arrays like: (after using built array and turned row to column): //startvolt= 0, stop volt=3, step size=1, number of points= 3// Voltage Current 0 84 1 85 2 86 3 87 0 90 1 91 2 92 3 93 0 100 1 101 2 102 3 103 I want to cut the columns (or the rows as u prefer) when the voltage reach again the starting value and and obtain something like: Voltage current1 current2 current3 0 84 90 100 1 85 91 101 ... ... ... ... I can easily delete from the voltage array the values but for the current i don't know what to do. My idea is to do a for loop where number of loops = number of points, where i put "subset of array" vi giving in input the length (Stop-start)/step, the index is (i * ((stop-start)/step))+1 but I don't know how to collect the subset of array every loop and then put them in different column. Thank you very much pesce

Hallo everybody, As it's monday I'm back to work and I can send you the VI with the data I use to load. I dysplayed in the front pannel the result of division, x*y and x+y and the only problem comes from the division, I wish someone can understand the problem, Thank you very much pesce Download File:post-4969-1148283155.txt Download File:post-4969-1148283188.vi

I saw your picture, I did my VI a lot of time in different way but the problem is still the division. I take the variable mca also for another calculation where there no other variable and i don't have problem. Thank u for your help! I wish too solve the problem Have good week end!

At the moment I'm at home and I can't check the VI you gave me, but I'll do it as soon as i come back to work. I know the picture is bad ad the wires look bad but trust me the are correct. I can add just a thing the program load a data from a file where i save them in form of spreadsheet file and before i save them i converted them to engineer number may be them problem is in the format but why only for the division? thank you

The data should be dbl 64bit

Hallo I need and help to solve this problem: I
