kronecker function

Kronecker Product

The generalized kronecker product of two matrices.

## S4 method for signature 'Expression,ANY'
kronecker(X, Y, FUN = "*", make.dimnames = FALSE, ...)

## S4 method for signature 'ANY,Expression'
kronecker(X, Y, FUN = "*", make.dimnames = FALSE, ...)

Arguments

• X: An Expression or matrix.
• Y: An Expression or matrix.
• FUN: Hardwired to "*" for the kronecker product.
• make.dimnames: (Unimplemented) Dimension names are not supported in Expression objects.
• ...: (Unimplemented) Optional arguments.

Returns

An Expression that represents the kronecker product.

Examples

X <- cbind(c(1,2), c(3,4))
Y <- Variable(2,2)
val <- cbind(c(5,6), c(7,8))

obj <- X %x% Y
prob <- Problem(Minimize(kronecker(X,Y)[1,1]), list(Y == val))
result <- solve(prob)
result$value
result$getValue(kronecker(X,Y))
