Matlab table to matrix.

table is a data type suitable for column-oriented or tabular data that is often stored as columns in a text file or in a spreadsheet. Tables consist of rows and column-oriented variables. Each variable in a table can have a different data type and a different size with the one restriction that each variable must have the same number of rows ... The best way to represent spreadsheet data in MATLAB® is in a table, which can store a mix of numeric and text data. However, sometimes you need to import spreadsheet data as a matrix, a cell array, or separate variables. Based on your data and the data type you need in the MATLAB® workspace, use one of these functions: Description example T = array2table (A) converts the m -by- n array, A , to an m -by- n table, T . Each column of A becomes a variable in T. array2table uses the input array name appended with the column number for the variable names in the table.T = table (var1,...,varN) creates a table from the input variables, var1,...,varN . Variables can be of different sizes and data types, but all variables must have the same number of rows. Actually I don't have much experience with tables, but if you can't figure it out you can always switch to using 1 cell array for the first column, and a ...T2 = addvars (T1,var1,...,varN) adds the arrays specified by var1,…,varN as new variables to the right of the last variable in T1. The input arrays var1,…,varN can be arrays having any data type, tables, and timetables. All input arguments must have the same number of rows as T1. For example, to add a column vector named A after the last ...

For example, a table variable can contain a matrix with multiple columns as long as it has the same number of rows as the other table variables. In MATLAB®, you can create tables and assign data to them in several ways. Create a table from input arrays by using the table function. Add variables to an existing table by using dot notation.
