Sum of array elements

Returns the sum of the elements of the first input

Usage

sum_MATLAB(A, dim)

# S4 method for array,missing
sum_MATLAB(A)

# S4 method for array,character
sum_MATLAB(A, dim)

# S4 method for array,numeric
sum_MATLAB(A, dim)

Arguments

A

vector, matrix or array

dim

dimention over which A is to be summed

Value

The total, row or column sum of A

Methods (by class)

• sum_MATLAB(A = array, dim = missing): Sum elements of A along the first array dimension whose size does not equal 1

• sum_MATLAB(A = array, dim = character): Computes the sum of all elements of A

• sum_MATLAB(A = array, dim = numeric): Computes the sum of all elements of A

Examples

x1 <- array(1:9, c(3, 3))
sum_MATLAB(x1)
#> [1]  6 15 24
sum_MATLAB(x1, "all")
#> [1] 45
sum_MATLAB(x1, 2)
#> [1] 12 15 18
