determine number of rows in 2-d array

[scientist]

I have a 2d array. How do I determine the number of rows? What if it were an n-d array? Thanks for any help anyone can offer.

Hi:

Use the ARRAY SIZE primitive in the Array Pallete. For a 2-d array, the ARRAY SIZE function will return an array with 2 elements. The first element is the number of rows, the second is the number of columns. For any N-dimension array, you can place a front panel array control and play around with the dimensions of the array and see how the ARRAY SIZE function returns the results.

Have fun

Hello

The following excerpt from LabView's help seems to answer your question:
The vi called Array Size in the LV array palette should do this job:

Array can be an n-dimensional array of any type.
size(s) is a 32-bit integer if array is one-dimensional (1D). If array is multidimensional, the returned value is a 1D array in which each element is a 32-bit integer representing the number of elements in the corresponding dimension of array. For example, if you wire a 3D 2x5x3 array to array, the function returns a three-element array containing [2,5,3].
--------
In a 2D array the first number is the Row, the second number is the column. I think the best way is to experiment by writing a little LV code, where you build an array of constants and use the Array
Size vi to read its output and see what it puts out.
