To find the rows from table or timetableAthat are found inBwith respect to a subset of variables, you can use column subscripting. For example, you can useismember(A(:,vars),B(:,vars)), wherevarsis a positive integer, a vector of positive integers, a variable name, a string array...

这里记录了我学习matlab的笔记,主要包括了简单的设置,数据类型,计算,format的使用,函数的使用,存储和文件操作,保存文件,绘图...,主要是学习了台湾大学郭彦福老师的matlab课程。其实matlab的语法跟c语言等编程语言的语法很像,我们只需要略微花一点点时间看看语法就可以基本掌握matlab的简单使用。

One way to do that is to use the Matlab load statement to load the data stored in a file named filename.ext to memory and assign it to a variable named filename. Note that the data is always stored in the form of a rectangular matrix since Matlab works only with matrices. Here, ...
Variable type: A vartype subscript that selects one variable of a specified type vartype("numeric")— One variable containing numeric values Note This name-value argument is not supported when the input data is a timetable. Timetables use the vector of row times as the sample points. To use...
