Thank you, but i have one problem : i want to sparate  2 D array becomes 1 D array , How can i do this .

[TiTou]

How do you want to do that ?
If you have 3 lines and 3 columns you want only 1 column of 9 ? If yes, there is a function "reshape array that do this very well 😉

What do you mean with "separate 2D array becomes 1D array"? Could you be a bit more precisely?

Now, i try to use this (untitled.vi). You can see 2 D array that is the output from the spreadsheet to array

but right now,  I want to use only 1D array because i will use DBL data type. Please help me

Thank you very much.

Use the "Index Array" function to select the necessary data. There you can define where the data is taken from (row and/or column as parameter).
