Name-value arguments must appear after other arguments, but the order of theīefore R2021a, use commas to separate each name and value, and enclose Name in quotes. The argument name and Value is the corresponding value. indexes find (A (row,:) 0) Tack on the second and other elements more to the right in this row. Most of the following examples show the use of indexing when referencing data in an array. This code will work: A 2 0 1 0 0 4 -9 0 5 0 0 0 2 0 -3 0 -3 2 0 0 1 2 0 0 6 linearIndexes for row 1 : size (A, 1) Find columns where A is nonzero. There are different kinds of indexing available depending on obj : basic indexing, advanced indexing and field access. Name1=Value1.,NameN=ValueN, where Name is ndarrays can be indexed using the standard Python x obj syntax, where x is the array and obj the selection. When working with text data in a table or a timetable, consider using a string array or a categorical array. Best practice is to avoid creating table or timetable variables that are character arrays. If you specify 'char' as a data type, then table preallocates the corresponding variable as a cell array of character vectors, not as a character array. Timetable with no variables and NaT for rowįor any other data type, the initial value is the value used by that type or class to "in-fill" unassigned elements of an array. Improved performance when assigning elements by subscripting into large table.I would like set the values of A corresponding to the idx to 0 and the values of B that do not correspond to the idx to 0, somethike like: A (idx) 0 and B (idx) 0. Improved performance when assigning elements by subscripting into table I have a vector let's say A 1:1:100', vector B 1:0.5:50.5' and a third vector with some indices such us idx 10 11 30 35 40 90 91 92 93 99'.Improved performance when assigning elements by subscripting with curly.Improved performance when subscripting with dot notation or multiple levels of.Dimension names cannot match reserved names B any( A ) tests along the first array dimension of A whose size does not equal 1, and determines if any element is a nonzero number or logical 1 ( true ).Variable names and dimension names must be unique.Variable names can contain leading and trailing whitespace characters.Specify Variable Names Using Any Characters.Build Table by Assigning Variables Individually.Specify Table Variables and Row Names Using String Arrays.
