T = array2table (A) 将 m × n 数组 A 转换为 m × n 表 T 。. A 的每一列都变成 T 的变量。. array2table 为表中的变量名称使用末尾追加了列号的输入数组名称。. 如果这些名称不是有效的 MATLAB ® 标识符， array2table 将使用 'Var1',...,'VarN' 形式的名称，其中 N 是 A 的列数 ... Accepted Answer: Peter Jarosi. If we import a .csv or Excel file using readtable, and then convert the table to an array as the following: Data=table2array (readtable ('Filename.csv')); We get an output like the following. This syntax process removed all the original labels of each column.C = table2cell (T) converts the table or timetable, T, to a cell array, C. Each variable in T becomes a column of cells in C. The output C does not include the table properties in T.Properties. If T is a table with row names, then C does not include the row names. If T is a timetable, then C does not include the row times.So that I can later interpolate the data by inserting the missing points. For example: In subtable {3,1} are missing data point times of 6 an 10 and i want to insert a row of NaN at row 6 and row 10 while not overwriting the other values. I tried creating 489 NaN-tables of 25x18 values with [:,1:17]=NaN and [:,18]=datatimepoints.
