nansum

Syntax

R = nansum(A)

R = nansum(A,dim)

Inputs

A

The argument from which to sum elements.

Type: double | complex | integer

Dimension: scalar | vector | matrix

dim

The dimension on which to sum, or 'all'

Default: first non-singleton dimension.

Type: integer

Dimension: scalar

Outputs

R

The sums of non-NaN elements.

Examples

Vector:

R = nansum([1,2,3,nan])

R = 6

Matrix with a specified dimension:

R = nansum([1,2,3,nan;4,nan,5,6],2)

R = [Matrix] 2 x 1
 6
15

Matrix with all dimensions:

R = sum([1,2,3,nan;4,nan,5,6],'all')

R = 21
