1)fix(x)？ : Truncation and rounding. > & gt？ Repair (? [3. 12? -3. 12]) ans？ = 3-3?
(2)floor(x): the largest integer not exceeding x (Gaussian rounding) > >? Floor (? [3. 12? -3. 12]) ans？ = 3-4?
(3)ceil(x)？ : the smallest integer greater than x >; & gt？ ceil(？ [3. 12? -3. 12]) ans？ = 4-3?
(4) rounding >>? Round (3. 12? -3. 12) ans？ = 0 & gt& gt？ Round ([3. 12? -3. 12]) ans？ = 3-3?
The specific usage of the four integer functions in MATLAB is as follows:
Matlab integer functions are:? Done,? Floor? ceil？ Round. Fix is rounded to zero, such as fix (-1.3) =-1; ? fix( 1.3)= 1； Floor is rounded to negative infinity, such as floor (-1.3) =-2; ? Floor (1.3) =1; Ceil is rounded to positive infinity, such as Ceil (-1.3) =-1; ? ceil( 1.3)= 2； Round is rounded to the nearest integer, such as round (-1.3) =-1; round(- 1.52)=-2； round( 1.3)= 1； round( 1.52)=2？
Chinese name: throughput, English name:
thruput
Definition: the amount of data (measured by bits, bytes, packets, etc.). For the network, equipment, port, virtual circuit or other facilities, it is successfully transmitted within a unit time. Throughput refers to the maximum data rate that a device can accept and forward without losing frames.
