Append operation


Hi folks,

So in one of my SciDB projects I tried to append one small array (let’s call it B) to an existing large array (e.g., A). For simplicity, let’s assume both A and B are two-dimensional. For example, A is 23: [[1,2,3], [4,5,6]] and B is 13: [[7,8,9]], and what I want to have is C = append(A,B,axis=0), a 3*3 array: [[1,2,3], [4,5,6], [7,8,9]].

My first try was to use the “concat” operator then I realized it was removed starting version 15. I dug the forum a bit and saw some suggestions on using “merge + redimension” to achieve “concat”, but still was not sure how to do that…

Any help would be appreciated!
