uint32

32-bit unsigned integer arrays

Description

Variables in MATLAB® of data type (class) uint32 are stored as 4-byte (32-bit) unsigned integers. For example:

y = uint32(10);
whos y
  Name      Size            Bytes  Class     Attributes

  y         1x1                 4  uint32

For more information on integer types, see Integers.

Creation

Some array creation functions allow you to specify the data type. For instance, zeros(100,'uint32') creates a 100-by-100 matrix of zeros of type uint32.

If you have an array of a different type, such as double or single, then you can convert that array to an array of type uint32 by using the uint32 function.

Syntax

Y = uint32(X)

Description

example

Y = uint32(X) converts the values in X to type uint32. Values outside the range [0,232-1] map to the nearest endpoint.

Input Arguments

expand all

Input array, specified as a scalar, vector, matrix, or multidimensional array.

Data Types: double | single | int8 | int16 | int32 | int64 | uint8 | uint16 | uint64 | logical | char
