Concat

Concat(A,B,I,J,K)

Concatenates lists or arrays.

When A and B are 1-D arrays,

Concat(A,B)

returns a list consisting of their elements. This form is often used to concatentate two indexes to obtain the elements for a third index.

When A and B are arbitrary arrays, where A has index I and B has index J, then

Concat(A,B,I,J,K)

concatenates (i.e., joins) arrays A and B, with the new result indexed by K. You must provide an index K whose length is the sum of the lengths of I and J. Often the index K is obtained using the first form of concatenate.

(new to 4.1) You can omit the K parameter:

Concat(A,B,I,J)

when you do so, the function creates a new local index named K for the result.
