Addition

Symbolic addition for LazyTensor objects or default addition for other types.

Usage

+x
x + y

Arguments

x, y

input for +.default() or +.LazyTensor().

Value

See value of +.default() or +.LazyTensor().

Details

If x or y is a LazyTensor, see +.LazyTensor(), else see +.default().

Note:

• the + operand is only a binary operator for LazyTensors: x + y.

• the + operand can be a unary or a binary operator for other types: + x or x + y.

Examples

if (FALSE) {
# R base operation
+5
1 + 3
# LazyTensor symbolic addition
x <- matrix(runif(150 * 3), 150, 3) # arbitrary R matrix, 150 rows, 3 columns
y <- matrix(runif(150 * 3), 150, 3) # arbitrary R matrix, 150 rows, 3 columns
x_i <- LazyTensor(x, index = 'i')   # creating LazyTensor from matrix x,
                                    # indexed by 'i'
y_j <- LazyTensor(y, index = 'j')   # creating LazyTensor from matrix y,
                                    # indexed by 'j'
Sum_xy <- x_i + y_j                 # symbolic matrix, 150 rows and 3 columns
