About Matlab String

When the input argument is a string array, the double function treats each element as the representation of a floating-point value. However, when the input is a character array, double instead converts each character to a number representing its Unicode value. As an alternative, use the str2double function.str2double is suitable when the input argument might be a string array, character

New features have been added to MATLAB recently String arrays were introduced in R2016b as Budo and gnovice already mentioned String arrays store pieces of text and provide a set of functions for working with text as data. You can index into, reshape, and concatenate strings arrays just as you can with arrays of any other type.

A string array is an array that contains multiple strings. Unlike character arrays, which are essentially arrays of characters, string arrays provide a more intuitive and flexible way to handle text data in MATLAB. For instance, consider the following comparison between a character vector and a string array

You also can use strlength on string arrays containing multiple strings and on cell arrays of character vectors.. The length function returns the size of the longest dimension of an array. For a string array, length returns the number of strings along the longest dimension of the array.

First, an array is an one-dimensional collection of information, just like a character array is! Secondly, when we use the multiplication operator on arrays, MATLAB wants to do what is called matrix multiplication. We will talk about this much more in the array and matrix topics, however, there is a way around this.

Split, Join, and Sort String Array. MATLAB provides a rich set of functions to work with string arrays. For example, you can use the split, join, and sort functions to rearrange the string array names so that the names are in alphabetical order by last name.. Split names on the space characters. Splitting changes names from a 5-by-1 string array to a 5-by-2 array.

String arrays are supported throughout MATLAB and MathWorks products. Functions that accept character arrays and cell arrays of character vectors as inputs also accept string arrays. Represent Text with Character Vectors. To store a 1-by-n sequence of characters as a character vector, using the char data type, enclose it in single quotes.

Creating a character string is quite simple in MATLAB. In fact, we have used it many times. Create cell array of strings from character array char Convert to character array string iscellstr Determine whether input is cell array of strings ischar Determine whether item is character array sprintf Format data into string

One of the new features I love in R2016b is string arrays, which give you a new way to handle text in MATLAB in addition to the familiar character arrays and cell arrays of character vectors. String arrays are most helpful when dealing with text in your data. In today's post I walk through some practical examples with text data to demonstrate

Character arrays and string arrays provide storage for text data in MATLAB . A character array is a sequence of characters, just as a numeric array is a sequence of numbers. A typical use is to store short pieces of text as character vectors , such as c 'Hello World' .
