Mar 20, 2018 · Unexpected behaviour of table2array. Documentation for table2array says, "table2array creates a homogeneous array, A, of the dominant data type. For example, if T contains double and single numeric data, table2array (T) returns an array with data type single." That surprises me. I would expect double to dominate single. A = table2array (T) converts the table or timetable, T, to a homogeneous array, A. The variables in T become columns in A. The output A does not include the table properties in T.Properties. If T is a table with row names, then A does not include the row names. If T is a timetable, then A does not include the row times.
example. T = table ('Size',sz,'VariableTypes',varTypes) creates a table and preallocates space for the variables that have data types you specify. sz is a two-element numeric array, where sz (1) specifies the number of rows and sz (2) specifies the number of variables. varTypes specifies the data types of the variables. example.Learn more about matlab, xlsx, xlsread, table2array, cell arrays, cell MATLAB I am working with .xlsx file and trying to get the values from it and multiply by another value(for tests, I do +1 to every cell, but it is not working as well).How to convert a table into an array.
