A^p 对A矩阵进行P次相乘操作A.^P 对A中的每一个元素进行取P次幂操作四、数值计算1、线性方程组求解(1)AX=B 的解可以用X=A\B求。XA=B的解可以用X= A/B求。如果A是m×n的矩阵,当m=n时可以找到唯一解,m<n,不定解,解中至多有m个非零元素。如果m>n,超定系统,至少找到一组 解。如果A是奇异的...
(1)AX=B的解可以用X=A\B求。XA=B的解可以用X= A/B求。如果A是m×n的矩阵,当m=n时可以找到唯一解,m<n,不定解,解中至多有m个非零元素。如果m>n,超定系统,至少找到一组解。如果A是奇异的,且AX=B有解,可以用X=pinv(A)×B返回最小二乘解 (2)AX=b, A=L×U,[L,U]=lu(A), X=U\(L...

Matlab内置了一些常量或约定名字(参考Matlab R2014a帮助文档“Special Values”、Matlab R2012a帮助文档“MATLAB/Functions/Mathematics/Math Constants”): Matlab基本算符和表达式(参考Matlab R2014a帮助文档“Operators and Elementary Operations”、Matlab R2012a帮助文档“MATLAB/User’s Guide/Programming Fundamentals/La...
不过M程序可能会经常出现索引错误,如果设置了stop if error(如果出错则停止,在Breakpoints菜单下),则程序的执行会停在出错的位置,并在MATLAB命令行窗口显示出错信息。下面列出了一些常用的调试方法。(1)设置或清除断点:使用快捷键F12。(2)执行:使用快捷键F5。(3)单步执行:使用快捷键F10。(4)step in:当遇见函数时...

首先来看Matlab的符号表(参考Matlab R2014a帮助文档“Symbol Reference”): 下图清晰的说明了Matlab的基本数据类型(类)(取自Matlab R2014a帮助文档“Fundamental MATLAB Classes”),其中double是默认数据类型,字符串用单引号‘’: Matlab是高级动态语言,变量(对象)在使用之前不需要声明,标识符的第一次出现视为变量的创...

You can use the run analysis button on the multicore tab to analyze the dataflow domain for simulation performance. It can profile the model, calculate the execution time of each block, find existing parallelism in the model, and partition it into multiple threads. It can suggest a latency va...
When I need to run a m-file, I usually press F5 key directly at the editor. However, after transferring to the 2013 version, I found that Matlab keeps echoing the name of the script file on the command window. As a person who got so used to the...
