How do I find the total number of elements in a multi dim array

How do I find the total number of elements in a single or multi dim array? For example, a 2x3 array has 6 elements, and a 2x3x4 has 24. How do I compute this very easily - is there a single VI that does this? David

Use "array size" (array palette) followed by "multiply array elements" (numeric palette)

(Works also equally well for 3D arrays and higher)

For a 1D array, just use "array size". 😉

Thanks... I was looking for the multiply, but couldn't find it because it doesn't look like a multiply sign - it looks like PI... but I'm not complaining... I like pie...

Similar to the S for addition, the P is standard for the product, see e.g. http://mathworld.wolfram.com/Product.html. 🙂
