How to visualize a 2D array of Vectors in Java

Question

I have a 2D array where each element is a fixed length vector. I'm using Java and need to visualize the 2D array in the form of a color matrix (as in Matlab). I want to visualize how the vectors in the 2D array change with time (example:visualized in a loop 0...100).

I need help on the following.

1. What is the best value to represent each element of the 2D array? (I've used the norm but I want to confirm whether this is standard estimate of the vector)
2. What is the best possible way to visualize the 2D array mentioned above? (I thought writing my own visualization using Swing. Is there any other methods available which would save time?)

Answer 1

What about int [ ] [ ] matrix = new int [ 100 ] [ 100 ] To visualize it you can simply print it:

for (int i=0; i<rows; i++) { for (int j=0;j<cols;j++) { System.out.println( matrix[i][j]+" "); } System.out.println(); }
