I'm working on a mxj patch that takes a float32 matrix with only one plane, but X and Y. I want to check each element in the matrix and perform calculations on the data. I was using getCell2d(), however that was very computationally strong. I then tried to copy this matrix to an array and work on the array instead. I would then go through this succesively with a for loop for X and Y. The code compiled, but when I run the code I get an arrayOutOfBounds exception error. The documentation does not explain how the matrix is changed into an array, so am I trying to access the array in the wrong fashion? I presumed it would be transfered into an array like array[640][480], but that does not seem to be the case. I'd really appriciate any help with this as it is driving me slowly towards insanity.

Here is the code I made.. In this case I am trying to keep track of the data in the array and output the lowest value.

public class matrixIf extends MaxObject {

        JitterMatrix jm = new JitterMatrix(s);

        int dimCap = dim[1]*dim[0];

        int offset[] = new int[]{0,0};

    //    jm.copyVectorToArray(dimCap,offset,test,dim[1]*dim[0],0);

                 tempFloat = test[j];

                    if(tempFloat < min)

                    {

                        min = tempFloat;

                    }

import com.cycling74.max.*;
import com.cycling74.jitter.*;
import java.util.*;

	public void jit_matrix(String s)
	{
		JitterMatrix jm = new JitterMatrix(s);
		int dim[] = jm.getDim();
		int dimCap = dim[1]*dim[0];
		float min = 0;
		float[] test = {};
		float tempFloat = 0;
		int offset[] = new int[]{0,0};
	    jm.copyMatrixToArray(test);
	//	jm.copyVectorToArray(dimCap,offset,test,dim[1]*dim[0],0);

				  tempFloat = test[j];
					if(tempFloat < min)
					{
						min = tempFloat;

Just to add, I have checked how many elements are being populated and its returning 0, so I must be populating it in the wrong fashion.
