java實現(xiàn)矩陣的加-減-乘-轉(zhuǎn)置運算

1、import java.util.*;public class JuZhen / 創(chuàng)建矩陣public static int createJuZhen(int x, int y) Scanner input = new Scanner(System.in);System.out.println(請輸入 + x + 行 + y + 列的矩陣數(shù)據(jù)（行優(yōu)先）：);int array = new intxy;for (int i = 0; i array.length; i+)for (int j = 0; j arrayi.length; j+) arrayij = input.nextInt();

2、return array;/ 矩陣輸出public static void outputJuZhen(int list) for (int i = 0; i list.length; i+) for (int j = 0; j listi.length; j+) System.out.print(listij + );System.out.println();/ 矩陣求和public static int addJuZhen(int list1, int list2) int list3 = new intlist1.lengthlist10.length;if (list1.length !

3、= list2.length | list10.length != list20.length) System.out.println(行數(shù)或列數(shù)不同的矩陣不能相加！并將返回0:！); else for (int i = 0; i list1.length; i+)for (int j = 0; j list10.length; j+)list3ij = list1ij + list2ij;return list3;/ 矩陣相乘public static int mulJuZhen(int list1, int list2) int list3 = new intlist1.lengthlis

4、t20.length;if (list1.length != list20.length | list10.length != list2.length)System.out.println(兩矩陣不能符合條件相乘！并將返回0:！);elsefor (int i = 0; i list1.length; i+)for (int j = 0; j list20.length; j+)for (int k = 0; k list20.length; k+)list3ij += list1ik * list2kj;return list3;/ 矩陣相減public static int substr

5、actJuZhen(int list1, int list2) int list5 = new intlist1.lengthlist10.length;if (list1.length != list2.length | list10.length != list20.length) System.out.println(行數(shù)或列數(shù)不同的矩陣不能相加！并將返回0:！); else for (int i = 0; i list1.length; i+)for (int j = 0; j list10.length; j+)list5ij = list1ij - list2ij;return l

6、ist5;/ 矩陣轉(zhuǎn)置public static int zhuanzhiJuZhen(int list) int list6 = new intlist.lengthlist0.length;for (int i = 0; i list.length; i+)for (int j = 0; j list0.length; j+)list6ij = listji;return list6;/ Main函數(shù)測試public static void main(String args) Scanner input = new Scanner(System.in);System.out.println

7、(請輸入所要創(chuàng)建第一個矩陣的行數(shù)和列數(shù)（如：3 3）：);int x = input.nextInt();int y = input.nextInt();int list1 = createJuZhen(x, y);/ 創(chuàng)建矩陣1System.out.println(請輸入所要創(chuàng)建第2個矩陣的行數(shù)和列數(shù)（如：3 3）：);x = input.nextInt();y = input.nextInt();int list2 = createJuZhen(x, y);/ 創(chuàng)建矩陣2int list3 = addJuZhen(list1, list2); / 矩陣相加int list4 = mulJu

8、Zhen(list1, list2); / 矩陣相乘int list5 = substractJuZhen(list1, list2);/ 矩陣相減int list6 = zhuanzhiJuZhen(list1);/ 矩陣轉(zhuǎn)置int list7 = zhuanzhiJuZhen(list2);/ 矩陣轉(zhuǎn)置/ 輸出結(jié)果System.out.println(矩陣1為：);outputJuZhen(list1);System.out.println(矩陣2為：);outputJuZhen(list2);System.out.println(矩陣1與矩陣2相加為：);outputJuZhen(list3);System.out.println(矩陣1與矩陣2相減為：);outputJuZhen(list5);System.out.println(矩
