How to convert string with numbers into 2D boolean array

[OnlyOne]

Hello,

i have as input a string with comma separated numbers 1..192 (starting at 1).

This string has to be converted into a 2D-boolean array. Each numer that appears should be true, the rest false.

The 2D array consists 4 times of 0..47 booleans.

Numbers 1..48        --> [0..47]  [0]
Numbers 49..96     --> [0..47]  [1]
Numbers 97..144   --> [0..47]  [2]
Numbers 145..192 --> [0..47]  [3]

So a input string of "1, 49, 97,145" should set all [0][0..3] to true.

How can this be easy/fast solved?

Thanks for help

Break the string of numbers into an array of numbers.  (Spreasheet String to Array).

In a For Loop, index through each number in that array.  Use In Range and Coerce to see if it is in the range of numbers.  (You might want to put this in a For Loop as well auto indexing through the ranges).  If it is in Range, then use Replace Array subset to turn the corresponding element into a True.  If not, do nothing.  Maintain the boolean array in a shift register.

Repeat that step for each number in your array.

(Is this a class assignment?)

Hi,

thanks for the help. It is almoste working,

Now i have four "In Range and Coerce" for the for ranges which create four arrays.

Currently i have a Buld Array" to create a 2D-Array of the four 1D arrays.

But: How can i change the 2D array that it its not a[0..3[0..47] but a [0..47[0..3] array?

Thx

Can you attach the VI you have so far?

If I can see how you have the data structured, then I can propose an idea of how to work with it.

Solved.

I searched "Transpose 2D Array"
