java坐标越界：BuffereImage（getrgb）

Question

我必须先找到图像的矩阵，我有这个代码，这给了我一个错误L[row][col] = image.getRGB(row, col); the error is“java.lang.ArrayIndexOutOfBoundsException:坐标超出范围！” 这个错误的原因是什么

import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;

import javax.imageio.ImageIO;

import Jama.EigenvalueDecomposition;
import Jama.Matrix;

public class eigenvalues {

    double L[][], A[];

    public static void main(String[] args) throws IOException { 
        File file = new File("C:\\Users\\lina\\workspace\\eigen\\koala.jpg");

        BufferedImage image= ImageIO.read(file);
        int width = image.getWidth();
        int height = image.getHeight();
        double[][] L = new double[height][width];

        for (int row = 0; row < height; row++) {
            for (int col = 0; col < width; col++) {
                L[row][col] = image.getRGB(row, col);
            }
        }
        Matrix A=new Matrix(L);
        EigenvalueDecomposition e = A.eig();
        Matrix V = e.getV();
        Matrix D = e.getD();
        System.out.print("A =");
        A.print(9, 6);
        System.out.print("D =");
        D.print(9, 6);
        System.out.print("V =");
        V.print(9, 6);
