How to Load A String List In Matlab?

8 minutes read

To load a string list in MATLAB, you can use the textread function. This function reads data from a text file and stores it in an array. You can specify the format of the data you want to read, such as strings.


First, create a text file with your string list, with each string on a new line. Then, use the textread function to load the strings into a cell array in MATLAB. Specify the file name, the format of the data (in this case %s for strings), and the number of lines to read.


Here is an example code snippet to load a string list from a text file named string_list.txt:

1
2
3
4
5
6
% Load the string list from text file
fid = fopen('string_list.txt', 'r');
string_list = textread('string_list.txt', '%s', 'delimiter', '\n');

% Display the string list
disp(string_list);


Run this code in MATLAB, and it will load the string list from the text file into the cell array string_list. You can then use this array in your MATLAB code for further processing or analysis.

What is the difference between a string list and a cell array of strings in Matlab?

In MATLAB, a string list is a simple array where each element is a string. It can be created using the string data type introduced in R2016b. It provides a more efficient and convenient way to work with strings compared to the traditional character arrays.


A cell array of strings, on the other hand, is a type of MATLAB array where each element can be of a different data type, including strings. Cell arrays are more general-purpose containers that can hold different types of data whereas a string list can only hold strings.


In summary, the main difference between a string list and a cell array of strings in MATLAB is that a string list is a specialized type of array that can only hold strings, while a cell array of strings is a more general-purpose container that can hold different types of data including strings.


How to remove elements from a string list in Matlab?

You can remove elements from a string list in MATLAB by using the remove function. Here is an example:

1
2
3
4
5
6
7
% Create a string list
strList = ["apple", "banana", "cherry", "date", "fig"];

% Remove an element by index
strList.remove(3);

disp(strList);


In this example, the element "cherry" is removed from the string list strList. You can also remove elements by value using the remove function. For example:

1
2
3
4
5
6
7
% Create a string list
strList = ["apple", "banana", "cherry", "date", "fig"];

% Remove an element by value
strList.remove("banana");

disp(strList);


In this example, the element "banana" is removed from the string list strList.


What is the purpose of a string list in Matlab?

A string list in Matlab is used to store a collection of strings in a sequential order. It can be used to organize and manage a set of strings, allowing for easy access and manipulation of individual elements within the list. String lists are particularly useful when working with textual data or when dealing with a large number of strings that need to be processed or analyzed in some way.


What are some common functions used with string lists in Matlab?

  1. Concatenating strings: Using the strjoin function allows you to concatenate all strings in a string list into a single string with a specified delimiter.
  2. Splitting strings: The strsplit function allows you to split a single string into a list of strings using a specified delimiter.
  3. Searching for specific strings: Functions like strcmp or contains can be used to search for specific strings within a string list.
  4. Sorting strings: The sort function can be used to sort a string list alphabetically or numerically.
  5. Removing duplicates: The unique function can be used to remove duplicate strings within a string list.
  6. Replacing substrings: The strrep function allows you to replace specific substring within a string list with a new substring.
  7. Counting occurrences: The count function can be used to count the occurrences of a specific substring within a string list.


What is the default data type of a string list in Matlab?

In MATLAB, the default data type of a string list is a cell array of strings. Each element in the cell array is a string data type.
