convert data in the text file to table in DBL

[sean1985]

well.

because all of my data from the text i read contains of some values, implies they won't be zero.

By using mike.vi, it consists of 0.00 value in my labview table.

How is this so?

Hi sean1985,

if you have an empty string and you convert it to a dbl, you will get "0.00". And because of there are some empty fields in your file, you get all the "0.00" values.

because some of my data from my .txt is positive. Thus some of the data in the table of labview is 0.00

mike,

i have alter some changes previously to \s\s. \s\s format will contribute to a column of 0.00 in my table

whereas \s\s\s cannot read in positive values (because there will be no sign) which then treat it as empty field, and in terms output as 0.00

Hi sean1985,

there is only one empty field. If you read your data as 1D array and delete the first elements, then you have 1024 elements in your array. You can create a table of it with the reshape array function. See the attached picture.

Hope it helps.

In all of your string constants where you have \s, the display mode is not correct. Right click and select '\' Codes Display (and then reenter the correct data). A \s is the '\' Code way to enter a space character. You could leave the string constants in normal display and simply enter the correct number of spaces by hitting the space bar but using the '\' code display makes it easier to just look at the diagram and see how many spaces are being used.

what is "\s\s " means? \s\s means 2 spacing? where can learnt more about this notation. I never seen it before? can u direct me?

Hi Sean,

open Labview help, go to Index tab, search for "Backslash" and choose the only one entry for this topic...

Can also be found via "format specifier syntax" and clicking "insert non-displayable characters in strings" (last paragraph). "Format specifier syntax" is linked in help of all string-formatting functions.
