The reshape function changes the size and shape of an array. For example, reshape a 3-by-4 matrix to a 2-by-6 matrix. A = [1 4 7 10; 2 5 8 11; 3 6 9 12] A = 3×4 1 4 7 10 2 5 8 11 3 6 9 12. B = reshape (A,2,6) B = 2×6 1 3 5 7 9 11 2 4 6 8 10 12. As long as the number of elements in each shape are the same, you can reshape them into an array ...Feb 5, 2018 · To convert a table to a matrix, use the “table2array” function.

Description. example. A = readmatrix (filename) creates an array by reading column-oriented data from a file. The readmatrix function performs automatic detection of import parameters for your file. readmatrix determines the file format from the file extension: .txt, .dat, or .csv for delimited text files. When you are using LiveScript, disp() displays a whole table in a scrolling region (or at least something more than 1000 lines). But if you are not using LiveScript, then disp() of a table displays only something like 100 lines and then gives you a link to click to display the entire table. That link uses displayWholeObj() to do the work.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.
