nancumsum
This function returns the cumulative sum of the values of a matrix
Syntax
s = nancumsum(x,orient)
Arguments
- x
x is a numerical vector or matrix.
- orient
is an optional parameter. The possible values are '*', 1, 2, 'r' or 'c'.
- s
numerical scalar or vector. It contains the cumulative sum of the values of
x
, ignoring the NAN's.
Description
This function returns in scalar or vector s
the cumulative
sum of the values (ignoring the NANs) of a vector or
matrix (real or complex) x
.
This function for a vector or a matrix x
, s=nancumsum(x)
(or, equivalently s=nancumsum(x,'*')
) returns in scalar s
the cumulative sum (ignoring the NANs) of all the entries
of x
taken columnwise.
s=nancumsum(x,'r')
(or, equivalently, s=nancumsum(x,1)
)
returns in s
the cumulative sum
(ignoring the NANs) of the rows of x
:
s(:,i)=nancumsum(x(:,i)
)
s=nancumsum(x,'c') (or, equivalently, s=nancumsum(x,2))
returns in s
the cumulative sum
(ignoring NANs) of the columns of x
:
s(i,:)=nancumsum(x(i,:))
Examples
a=[1 2 %nan;%nan 5 6] s=nancumsum(a) s=nancumsum(a,'r') s=nancumsum(a,'c')
