how to calculate the sum of the values of some columns of a table

[achfire]

hi

i want to get in the column averages just the average of the values of some columns not all the columns of the table.what i have to change exactly in this block diagram.even if the size of the table is 25,i want the division to be the number of values in each column(= number of rows)

just like that:

Check for "Mean.vi" in Mathematics palette. Replace your code inside the for loop with that vi.

Something like this you should have.

but it doesn't change anything,how could i get the values of just some columns, number 2 and 5 for example

[P@Anand]

For that you have to index the array like this.

I would recommend you to go through some basic training materials in LabVIEW which you may find here.

Good luck!

i did exactely what u told me, i think i missed something because i don't get the average value of the rows i want

[P@Anand]

I didn't use a Transpose array

[achfire]

if i don't use transpose array i will get the average value of each row, i want the average of columns

[achfire]

even if i used the 3rd and 5th columns,i get 4 values in the column averages  which is wrong.i want the average values of the column 3 and 5.so just 2 values

[P@Anand]

You cannot get 4 elements unless you have 4 values in the array from which you are feeding the index.

here is exactly what i get with the previous blockdiagram
