Concatenating several matrices from an ArrayList

Mar 19 2014 | 3:58 am

Hello everybody,
I am currently working on a project with a 3d laser scanner with a 270 degree scan angle. For each one of the passes of the scanner I am storing the data on a separate matrix using a java container (ArrayList). In order to reconstruct the data I am outputting the matrix one by one. However, in order to ease the process I would like to concatenate matrices with the following criteria:
a)an offset
b)a range

Implementing this has been quite straight forward:
public void flushMatricesOffset(int offset, int range){
for(int i=offset;i<=range;i++){
JitterMatrix m = (JitterMatrix)matrices.get(i);
outlet(0,"jit_matrix", m.getName());

However I am finding difficulties how to concatenate each matrix to a single output matrix. My logic would be:
1-create a Jitter Matrix that would work as the final ‘output’ matrix
2-each iteration of the loop uses the variable m, a JitterMatrix, to hold temporarily the desired index of the container
3-the variable m is concatenated to the ‘output’ matrix. And so on for each pass.

I have taken a look into the jit.concat object and seems to be the best option for this task? any suggestions of how to proceed?

thank you very much!
