# arrayConcat(a,b)

Joins together arrays.

### Syntax

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

### Usage

Use this to join multiple arrays into a new array of same shape.

### Location

menu: veeos ==> Math ==> Arrays ==> arrayConcat

library: mathLib

### Example

                   1  2  3   3  4           1  2  3  3  4
    o_arrayConcat( 4  5  6 , 3  4 ) yields  4  5  6  3  4
                   7  8  9   3  4           7  8  9  3  4

                   1  2   3  4           1  2
    o_arrayConcat( 4  5 , 3  4 ) yields  4  5
                   7  8                  7  8
                                         3  4
                                         3  4

### Notes

While the built-in "concat()" function can join together arrays, it always flattens them into a 1D array. This function constructs a new array of same shape with the two input arrays joined side-by-side. Orientation is automatic (dimension that doesn't match gets extended. If all dimensions match then highest dim gets extended). Note that loops are not used so this function is fast.
