The recommended way to rename variables is to use the renamevars function. For example, rename the LastName variable of T to PatientName. Get T = renamevars(T,"LastName","PatientName") T=100×6 table PatientName Age Height Weight Smoker BloodPressure ___ ___ ___ ___ ___...
该警告信息表明,MATLAB在读取文件(如CSV或Excel文件)以创建表格(table)时,文件中的列标题包含了一些MATLAB不支持的字符(如空格、特殊字符等)。为了符合MATLAB的变量命名规则,MATLAB自动修改了这些列标题。原始列标题被保存在表格的VariableDescriptions属性中。 2. 分析为何会出现该警告 MATLAB的变量命名规则要求变量名必须...
T = table(var1,...,varN) T = table('Size',sz,'VariableTypes',varTypes) T = table(___,Name,Value) T = table Description T = table(var1,...,varN)creates a table from the input variablesvar1,...,varN. The variables can have different sizes and data types, but all variables ...
Example:T = renamevars(T,'Var1','Location')changes the name of the table variable'Var1'to'Location'. Example:T = renamevars(T,["Var1","Var2"],["Latitude","Longitude"])changes the names of two table variables. Example:T = renamevars(T,1:width(T),newNames)renames all of the ...

decimate_func = @(x) x(1:data_step:end); T1 = varfun(decimate_func,T); T2 = T(1:data_step:end,:); T is a table of double and string columns. Expected T1 to be te same as T2, however T1 modifies the column names by adding a "Fun_" to the variable names. why?
