Calling Sequence

y=int8(X)
y=int16(X)
y=int32(X)
y=uint8(X)
y=uint16(X)
y=uint32(X)

Arguments

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)
