arithmetic.multiply: Multiplication

Description

Symbolic multiplication for LazyTensor objects or default multiplication otherwise.

Usage

x * y

Value

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

Arguments

x, y

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

Author

Details

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

Examples

if (FALSE) {
# R base operation
+5
1 + 3
# LazyTensor symbolic multiplication
x <- matrix(runif(150 * 3), 150, 3) # arbitrary R matrix, 150 rows, 3 columns
y <- matrix(runif(250 * 3), 250, 3) # arbitrary R matrix, 250 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'
x_times_y <- x_i * y_j              # symbolic matrix
