# 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')```

• nansum — Sum of values ignoring NAN's
• cumsum — суммирование элементов массива с накоплением
