# concat3D(a,b)

Joins together 3D arrays.

NOTE - this function is maintained for backward-compatibility but is now deprecated in favor of arrayConcat(a,b)

### Syntax

o_concat3D(a,b)
  a: array 3D any - first input array
  b: array 3D any - second input array
  return: array 3D any - the two input arrays concatenated together

### Usage

Use this to join multiple 3D arrays into a new 3D array.

### Location

menu: veeos ==> Math ==> concat3D

library: dataLib

### Example

See example in veeos menu.

### Notes

While the built-in "concat()" function can join together 3D arrays, it always flattens them into a 1D array. This function maintains the 3D shape and automatically determines the correct orientation. Note that two of the dimensions need to match before it is feasible to join the arrays. If no two match then an error is raised. Note that loops are not used so this function is fast.

### Reference
