int8
8-bit signed integer arrays
Description
Variables in MATLAB® of data type (class) int8
are stored as 1-byte (8-bit)
signed integers. For example:
y = int8(10);
whos y

For more information on integer types, see Integers.
Creation
Some array creation functions allow you to specify the data type. For instance,
zeros(100,'int8')
creates a 100-by-100 matrix of zeros of type
int8
.
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
int8
by using the int8
function.
