int16 - conversion to 2 bytes integer representation

int32 - conversion to 4 bytes integer representation

uint8 - conversion to one byte unsigned integer representation

uint16 - conversion to 2 bytes unsigned integer representation

uint32 - conversion to 4 bytes unsigned integer representation

Calling Sequence

y=int8(X)

y=int16(X)

y=int32(X)

y=uint8(X)

y=uint16(X)

y=uint32(X)

Parameters

• X : matrix of floats or integers
• y : matrix of integers coded on one, two or four bytes.

Description

converts and stores data two one, two or four bytes integers. These data types are specialy useful to store big objects such as images, long signals,...

y=int8(X) : return numbers in the range [-128,127]

y=uint8(X) : return numbers in the range [0,255]

y=int16(X) : return numbers in the range [-32768,32767]

y=uint16(X) : return numbers in the range [0, 65535]

y=int32(X) : return numbers in the range [-2147483648,2147483647]

y=uint32(X) : return numbers in the range [0, 4294967295]

Examples

int8([1 -120 127 312])
uint8([1 -120 127 312])

x=int32(-200:100:400)
int8(x)
