For example, you can customize parentheses indexing by inheriting from matlab. You can also overload the subsref and subsasgn functions in your classes, but this technique requires you to overload parentheses, dot, and brace indexing, even if you need to customize only one behavior. Using the modular indexing classes is the recommended procedure whenever possible.

IndexingOperation to describe the type of a given indexing operation and the indices referenced by that operation. IndexingOperation instances appear as arguments for methods of these classes:. For information on class attributes, see Class Attributes. The property values are set at creation. Type of indexing operation, identified as an IndexingOperationType enumeration member:. List of indices referenced in indexing operation, specified as a cell array. When the Type property is Dot , accessing this property results in an error. Name of the field referenced in a dot indexing operation, specified as a string. When the Type property has any value except for Dot , accessing this property results in an error. Expressions with more than one indexing operation generate arrays of IndexingOperation instances. Type : IndexingOperationType. Name : "PrivateProp".

Now that you know the locations of the elements meeting the condition, you can inspect the individual values using ind as the index array. IndexingOperation class Package: matlab, matlab indexing.

This page shows techniques to extract and view portions of a tall array. Use the head function to extract the first rows in a tall array. Similarly, you can use the tail function to extract the bottom rows in a tall array. All tall arrays support parentheses indexing.

Which form you use is mostly a matter of style and your sense of the readability of your code, but it also depends on whether or not you need the actual index values for something else in the computation. There is often confusion over how to select scattered elements from a matrix. Indexing into a matrix with a single subscript in this way is often called linear indexing. You can inherit from these classes independently. See Also matlab. Another indexing variation, logical indexing , has proven to be both useful and expressive. For example, create a tall table for the outages. Choose a web site to get translated content where available and see local events and offers. See Customize Parentheses Indexing for an example of this behavior. For example, select all the columns in the third row of A :. Another MATLAB user posted this question: I want to get the maximum of each row, which isn't really a problem, but afterwards I want to set all the other elements to zero.

IndexingOperation instances appear as arguments for methods of these classes:. Each class is responsible for one group of indexing operations:. Based on your location, we recommend that you select:. RedefinesDot —dot property reference, method call, and assignment. Main Content. IndexingOperation instances appear as arguments for methods of these classes: matlab. You must use gather to evaluate the indexing operation. For example, suppose you want to temporarily replace NaN values with zeros, perform some computation, and then put the NaN values back in their original locations. Search MathWorks.
