More Answers (1) There are two ways to converta table to a (numeric in this case) array: 1) call table2array 2) use {} subscripting for the variables you want to extract. You say, "all data converted to be from 0 to 255". Tables are all about mixed data types - one container with doubles, uints, strings, whatever in it.

Expanding a Matrix. You can add one or more elements to a matrix by placing them outside of the existing row and column index boundaries. MATLAB automatically pads the matrix with zeros to keep it rectangular. For example, create a 2-by-3 matrix and add an additional row and column to it by inserting an element in the (3,4) position.

Copy. plot (T1.Date,T1.YourDataVarName) where T1, YourDataVarName are the appropriate table variable name and whatever variable it is in the table you wish plotted vs time. Magic will happen... Read the sections on tables and how to dereference them--there are a number of alternatives depending on the objectives at hand.If a variable in T1 is a table itself, then splitvars uses the names of its variables (and, if necessary, the name of that table) to make unique names for the new variables in T2. To merge variables into one multicolumn variable, use the mergevars function. example. T2 = splitvars (T1,vars) splits only the table variables specified by vars.0. T = table (T1,T2,T3) only works if all three tables have exactly the same number of columns AND exactly the same number of rows, and all columns are the same data type. If I had a 1000 tables, it would be nice if Matlab could index them: T (1) = T1; T (2) = T2; Create a vertical table output displaying in the first column the pressure and the second column the current.
