diff
Difference and discrete derivative
Calling Sequence
y=diff(x) y=diff(x [,n [,dim]])
Arguments
- x
vector or matrix (real, complex, sparse or polynomial)
- n
integer the order of differentiation
- dim
integer or character string with values "r","c" and "*"
- y
scalar or vector
Description
y=diff(x)
compute the difference function
y=x(2:$)-x(1:$-1)
diff(x,n,dim)
is the n
th
difference function along dimension dim
.
diff(x,n,"*")
is equivalent to
diff(x(:),n).
Default value for n
is 1. Default value for
dim
is "*"
.
dim='r'
is equivalent to dim=1
and dim='c'
is equivalent to
dim=2
.
