reverse

Reverse order of characters in strings

Syntax

newStr = reverse(str)

Description

newStr = reverse(str) reverses the order of the characters in str.

Examples

Reverse Strings

Reverse the strings in a string array and find strings that read the same when reversed.

str = ["airport","control tower","radar","runway"]

str = 1×4 string
    "airport"    "control tower"    "radar"    "runway"

newStr = reverse(str)

newStr = 1×4 string
    "tropria"    "rewot lortnoc"    "radar"    "yawnur"

tf = (newStr == str)

tf = 1×4 logical array

   0   0   1   0

str(tf)

ans = 
"radar"

Input Arguments

str — Input text

string array | character vector | cell array of character vectors

Input text, specified as a string array, character vector, or cell array of character vectors.

Output Arguments

newStr — Output text

string array | character vector | cell array of character vectors

Output text, returned as a string array, a character vector, or a cell array of character vectors. str and newStr are the same data type.

Extended Capabilities

Tall Arrays

Calculate with arrays that have more rows than fit in memory.

The reverse function fully supports tall arrays. For more information, see Tall Arrays.

C/C++ Code Generation

Generate C and C++ code using MATLAB® Coder™.

Usage notes and limitations:

• str must be a string scalar, a character vector, or a cell array containing not more than one character vector.

Thread-Based Environment

Run code in the background using MATLAB® backgroundPool or accelerate code with Parallel Computing Toolbox™ ThreadPool.

This function fully supports thread-based environments. For more information, see Run MATLAB Functions in Thread-Based Environment.

Distributed Arrays

Partition large arrays across the combined memory of your cluster using Parallel Computing Toolbox™.

This function fully supports distributed arrays. For more information, see Run MATLAB Functions with Distributed Arrays (Parallel Computing Toolbox).
