Description

A sequence of kronecker products

Usage

kronecker.seq(X, FUN = "*", make.dimnames = FALSE, ...)
kronecker_seq(X, FUN = "*", make.dimnames = FALSE, ...)
kroneckerSeq(X, FUN = "*", make.dimnames = FALSE, ...)
KroneckerSeq(X, FUN = "*", make.dimnames = FALSE, ...)

Value

A matrix or array

Arguments

X

A list of numeric matrices or arrays

FUN

a function; it may be a quoted string.

make.dimnames

Provide dimnames that are the product of the dimnames of X and Y.

...

optional arguments to be passed to FUN.

Examples

x1 = matrix(rnorm(16), nrow = 4)
x2 = matrix(rnorm(25), nrow = 5)
x3 = matrix(rnorm(36), nrow = 6)
x4 = matrix(rnorm(49), nrow = 7)
p1 = x1 %x% x2 %x% x3 %x% x4
p2 = kronecker.seq(list(x1, x2, x3, x4))
all.equal(p1, p2)
