Create a table and remove variables one at a time. You can specify variables by name or by position in the table. Read data from a spreadsheet into a table. Display the first three rows. Get T1 = readtable('outages.csv'); head(T1,3) Region OutageTime Loss Customers RestorationTime ...
Delete Variables To delete table variables, use the removevars function. Delete the Systolic and Diastolic table variables. Get T = removevars(T,["Systolic","Diastolic"]); head(T,5) LastName Age SelfAssessedHealthStatus Smoker Height Weight BMI BloodPressure ___ ___ ___ ___ ___ __...
save(filename) saves all variables from the current workspace in a binary MATLAB® file (MAT-file) named filename. If filename exists, save overwrites the file. example save(filename,variables) saves only the variables or fields of a structure array specified by variables. example save(file...

“Matlab”是“MatrixLaboratory” 的缩写,中文“矩阵实验室”,是强大的数学工具。本文侧重于Matlab的编程语言侧面,讲述Matlab的基本语法,以及用Matlab语言进行程序设计。值得一提的是,Matlab从R2014a版本开始支持中文语言了! 1.基本概念 Matlab默认启动后界面: ...
Create a table from input arrays by using the table function. Add variables to an existing table by using dot notation. Assign variables to an empty table. Preallocate a table and fill in its data later. Convert variables to tables by using the array2table, cell2table, or struct2table fu...
Save all variables from the workspace in a binary MAT-file, test.mat. If filename is a variable, use function syntax. Get filename = "test.mat"; save(filename) Otherwise, you also can use command syntax. Get save test.mat Remove the variables from the workspace, and then retrieve ...

To use the dummy variables in a regression model, you must either delete a column (to create a reference group) or fit a regression model with no intercept term. For the gender example, you need only one dummy variable to represent two genders. Notice what happens if you add an intercept...
A two-dimensional array is effectively a table of data, not restricted to numeric data. If arrays are stacked in the third dimension, then they are three-dimensional arrays. Matrices are two-dimensional arrays that contain only numeric data or mathematical expressions where the variables of the ...
