MATLAB有很多内置的矩阵处理函数，能够很好的实现对于矩阵的计算，可以用于计算一些简单的运算。

本人基于MATLAB的GUI界面设计了一个操作简单矩阵计算器，能够实现矩阵的加、减、乘、除、点乘、转置、求秩、求矩阵行列式、特征值、特征向量、LU分解、矩阵的最简形化简等功能，具体的界面如下：

点击输入矩阵A和矩阵B的数据——点击相应的功能按键——开始计算——出现结果显示——点击清除可以清除输入——点击关闭可以关闭当前的GUI界面。需要基于MATLAB的矩阵计算器的GUI计算界面完整GUI程序，可以进行赞赏后截图（20元及以上），进行联系，或者点击微信公众号云龙派的“联系掌门”菜单进行联系，或者在公众号内回复截图，几小时内会回复。界面编程不易，还请见谅！

1.操作示例

（1）输入矩阵，执行矩阵的乘法运算A*B，输出结果

（2）计算矩阵A/B

（3）计算矩阵A的转置

（4）求矩阵A的逆矩阵

（5）求矩阵A的秩

（6）求矩阵A的特征值

（7）求矩阵A的特征值

（8）求矩阵A的特征向量

（9）矩阵A的LU分解矩阵

（10）矩阵A的最简形

2.GUI的部分程序如下

function varargout = juzhen(varargin)% JUZHEN MATLAB code for juzhen.fig%      JUZHEN, by itself, creates a new JUZHEN or raises the existing%      singleton*.%%      H = JUZHEN returns the handle to a new JUZHEN or the handle to%      the existing singleton*.%%      JUZHEN('CALLBACK',hObject,eventData,handles,...) calls the local%      function named CALLBACK in JUZHEN.M with the given input arguments.%%      JUZHEN('Property','Value',...) creates a new JUZHEN or raises the%      existing singleton*.  Starting from the left, property value pairs are%      applied to the GUI before juzhen_OpeningFcn gets called.
