int2str

Convert integers to characters

Syntax

chr = int2str(N)

Description

chr = int2str(N) treats N as a matrix of integers and converts it to a character array that represents the integers. If N contains floating-point values, int2str rounds them before conversion.

Examples

Convert Integers

Convert an integer.

chr = int2str(256)

chr = 
'256'

Round off a floating-point value and convert it.

chr = int2str(3.14159)

chr = 
'3'

Convert a numeric matrix.

chr = int2str([5 10 20;100 200 400])

chr = 2x13 char array
    '  5   10   20'
    '100  200  400'

Input Arguments

N — Input array

numeric matrix

Input array, specified as a numeric matrix.

Tips

• int2str returns character arrays only. Starting in R2016b, you can convert numeric arrays to string arrays using the string function.

Extended Capabilities

C/C++ Code Generation

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

Usage notes and limitations:

• Input array must be scalar at compile time.

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.

GPU Arrays

Accelerate code by running on a graphics processing unit (GPU) using Parallel Computing Toolbox™.

Usage notes and limitations:

• This function accepts GPU arrays, but does not run on a GPU.

For more information, see Run MATLAB Functions on a GPU (Parallel Computing Toolbox).
