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

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]
