matlab如何解决矩阵维度必须一致收藏
*改为.*我试过了没用还是提示矩阵维度必须一致。。。不知道该怎么办。。才接触matlab没多久希望大神帮忙

顶顶。。。。。。。。。。。。。
大家都来看看阿 啊啊啊啊啊啊啊啊啊啊啊啊啊啊
原因可能有二：其一、你输入的矩阵就不满足矩阵的运算法则；其二、对*与.*
^与.^理解不到位。详解如下：举个例子吧（在另外一个帖子上遇到的）首先代码应该改为：x=0:1:100;y=0.5./sqrt([81./(x.^2)+1].*[1+(x.^2)./36]);plot(x,y,'+-r');最后画图为：要分清*与.*的区别。其中点乘（.*）是指两个矩阵的元素一一对应相乘。而乘（*）是指矩阵AB相乘（A*B要满足矩阵相乘的法则，即A的列数与B的行数相等）。其他 /与./、^与.^也是这样的区别。例图：
如下图，x与y相乘明显是错误的！因为x的列数要与y的行数相等，矩阵x与矩阵y才可以相乘，这就是我说的其一原因（事实上原因而是原因一的特殊情况）。
线性代数要多复习。。。

Simulink里创建SCI通讯模块，错误：索引超出矩阵维度
此问题尚无答案
All Replies
求大神指教。
在MATLAB/Simulink里创建了SCI通讯的transmit和Receive模块，希望在目标板F28035的串口上收到数据后原原本本的再发送回来，在主机的串口调试助手上可以实现发送的内容再接收回来。如下图所示。F28035，SCI transmit，SCI receive都已配置好。
使用串口COM4
编译之后出现错误如下：
根据错误信息提示，我打开了c200hostsci_rx.m文件，PostPropagationSetup也找到具体位置，但是不知道该怎么修改。
