字符串,Cell数组,Table,Struct: 字符串,Cell数组,Table,Struct本质上都是数组。字符串的元素是char;Cell数组的元素是cell,cell相当于一个容器,其中可以存任意类型,如double型矩阵,字符串,甚至是cell,cell 的内容用{}提取;Table有点像数据库的表;Struct类似于C语言的结构体。请读者参考Matlab R2014a帮助文档“Funda...

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?

Table.Properties.VariableNames will add 3 dots "..." to long Variable Names, thereby shortening the actual name in the cell array, and making them useless to index into said table column. This might have to do with the way Tables are displayed when viewing them in the workspa...

I've presumed column names for the variables in columns based on your variable names above; match to suit what you have in the table. Rightfully, you should be able to input the data with the date/time interpreted as a MATLAB datetime variable in which case the Date column will be a si...
% Place each file name in a cell array - required in case the names have different lengths. % Note: We don't have to use rowfun, we may create the file name inside the loop. T2 = rowfun(@(x) {fullfile('E:', [x, '.txt'])}, T, 'InputVariables', 'Code', 'OutputVariableNa...
