sum
Sum of array elements
Syntax
Description
S = sum(
returns
the sum of the elements of A along the first array dimension whose
size does not equal 1.A
)
If
A
is a vector, thensum(A)
returns the sum of the elements.If
A
is a matrix, thensum(A)
returns a row vector containing the sum of each column.If
A
is a multidimensional array, thensum(A)
operates along the first array dimension whose size does not equal 1, treating the elements as vectors. This dimension becomes1
while the sizes of all other dimensions remain the same.
S = sum(
computes the sum of all elements of A
,'all'
)A
. This syntax is valid for
MATLAB® versions R2018b and later.
S = sum(___,
returns
the sum with a specified data type, using any of the input arguments
in the previous syntaxes. outtype
)outtype
can be 'default'
, 'double'
,
or 'native'
.
