1 sty 2018 · In MATLAB®, there are three primary approaches to accessing array elements based on their location (index) in the array. These approaches are indexing by position, linear indexing, and logical indexing. You can also use mixed indexing by combining both positional and logical indexing.
10 wrz 2011 · When you want to access selected elements of an array, use indexing. For example, consider the 4-by-4 matrix A : A = [1 2 3 4; 5 6 7 8; 9 10 11 12; 13 14 15 16]
To index into a table, specify rows and variables using either positions, names, or data types. The result can be either an array or a table. This topic describes the different table indexing syntaxes and when to use each type.
1 sty 2018 · In general, you can use indexing to access elements of any array in MATLAB regardless of its data type or dimensions. For example, directly access a column of a datetime array. t = [datetime(2018,1:5,1); datetime(2019,1:5,1)]
Indexing into a matrix is a means of selecting a subset of elements from the matrix. MATLAB has several indexing styles that are not only powerful and flexible, but also readable and expressive. Indexing is a key to MATLAB's effectiveness at capturing matrix-oriented ideas in understandable computer programs.
