Usage

ipu_matrix(mtx, row_targets, column_targets, ...)

Arguments

mtx	a matrix
row_targets	a vector of targets that the row sums must match
column_targets	a vector of targets that the column sums must match
...	additional arguments that are passed to 'ipu()'. See ipu for details.

Value

A matrix that matches row and column targets

Examples

mtx <- matrix(data = runif(9), nrow = 3, ncol = 3)
row_targets <- c(3, 4, 5)
column_targets <- c(5, 4, 3)
ipu_matrix(mtx, row_targets, column_targets)
