strjust

Justify strings

Syntax

newStr = strjust(str)

newStr = strjust(str,side)

Description

Note

pad is recommended over strjust because it provides greater flexibility and allows vectorization. For additional information, see Alternative Functionality.

newStr = strjust(str) returns a right-justified version of the text in str.

• If str has trailing whitespace characters, then they become leading whitespace characters in newStr.

• If str does not have trailing whitespace characters, then strjust returns str unaltered.

newStr = strjust(str,side) returns a version of the text that is justified on the side specified by side. The text in str can be justified on the left, right, or center.

Examples

Right-Justify Text

Create a string array in which some elements have trailing whitespace characters.

str1 = ["Skylab";
        "Mir   ";
        "ISS   "]

str1 = 3×1 string
    "Skylab"
    "Mir   "
    "ISS   "

Justify the text on the right. strjust does not alter the first element because "Skylab" has no whitespace.

str2 = strjust(str1)

str2 = 3×1 string
    "Skylab"
    "   Mir"
    "   ISS"

Center-Justify Text

Create a cell array of character vectors. Some of the character vectors have leading and trailing whitespace characters.

C1 = {'Euler    ';
      'Fibonacci';
      '    Gauss'}

C1 = 3×1 cell
    {'Euler    '}
    {'Fibonacci'}
    {'    Gauss'}

Center-justify the text. If a piece of text has leading or trailing whitespace, or both, then strjust adjusts the text to have an equal number of leading and trailing whitespace characters. strjust does not alter a piece of text when it has neither leading nor trailing whitespace.

C2 = strjust(C1,'center')

C2 = 3×1 cell
    {'  Euler  '}
    {'Fibonacci'}
    {'  Gauss  '}

Input Arguments

str — Input text

character array | cell array of character vectors | string array

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

side — Side to justify text on

'right' (default) | 'left' | 'center'

Side to justify text on, specified as 'left', 'right', or 'center'. The default behavior is to justify the text on the right.

Alternative Functionality

Update code that makes use of strjust to use pad instead. If justifying text left or right, also use strip to remove whitespace from the text first. For example:

Context	Not Recommended	Recommended
Right justification	strjust(A)	pad(strip(A),"left")
Left justification	strjust(A)	pad(strip(A),"right")
Center justification	strjust(A,"center")	pad(A,"both")

Extended Capabilities

C/C++ Code Generation

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

Usage notes and limitations:

• Input text must be a string scalar or a character vector.

• Generated code returns an empty output as a 1-by-0 character array.

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.
