Question about JAMA

["@lvin" <zurs@ms1.url.com.tw>]

Dear Sir,

 

I have a problem of programming with Jama

 

I write the following code and meet a ArrayIndexOutOfBoundsExceptions

Could anybody please tell me how to correct this problem?

 

Thank you in advance…

import Jama.*;


import Jama.*;

public class TestMat {
    public static void main(String[] args) {
		double[][] vals = {{2, 3, 1,7},{4, 2, 2, 3},{7, 9, 9, 1}};
		Matrix A = new Matrix(vals);
		System.out.println("The Matrix A is ");
		A.print(3, 0);
		System.out.println();
		
		int r = A.rank();
		System.out.println("Rank = " +r);
		System.out.println();
		
		System.out.println("The Transpose of A is ");
		Matrix T = (A.transpose());
		T.print(3, 0);
		System.out.println();
		
		
		System.out.println("The SVD of A is ");
		SingularValueDecomposition svd = A.svd();
/*		Matrix S = svd.getS();
		System.out.println("S is ");
		S.print(3, 0);
		System.out.println();
*/
		Matrix U = svd.getU();
		System.out.println("U is ");
		U.print(5, 0);
		System.out.println();
		
		Matrix UT = U.transpose();
		System.out.println("U' is ");
		UT.print(5, 0);
		System.out.println();
		
		Matrix UUT = U.times(UT);
		System.out.println("UU' is ");
		UUT.print(5, 0);
		System.out.println();
		

    }
