max_entries: Maximum

In anqif/CVXR: Disciplined Convex Optimization

Maximum

Description

The maximum of an expression.

Usage

max_entries(x, axis = NA_real_, keepdims = FALSE)

## S3 method for class 'Expression'
max(..., na.rm = FALSE)

Arguments

x	An Expression, vector, or matrix.
axis	(Optional) The dimension across which to apply the function: 1 indicates rows, 2 indicates columns, and NA indicates rows and columns. The default is NA.
keepdims	(Optional) Should dimensions be maintained when applying the atom along an axis? If FALSE, result will be collapsed into an n x 1 column vector. The default is FALSE.
...	Numeric scalar, vector, matrix, or Expression objects.
na.rm	(Unimplemented) A logical value indicating whether missing values should be removed.

Value

An Expression representing the maximum of the input.

Examples

x <- Variable(2)
val <- matrix(c(-5,-10))
prob <- Problem(Minimize(max_entries(x)), list(x == val))
result <- solve(prob)
result$value

A <- Variable(2,2)
val <- rbind(c(-5,2), c(-3,1))
prob <- Problem(Minimize(max_entries(A, axis = 1)[2,1]), list(A == val))
result <- solve(prob)
result$value
x <- Variable(2)
val <- matrix(c(-5,-10))
prob <- Problem(Minimize(max_entries(x)), list(x == val))
result <- solve(prob)
result$value

A <- Variable(2,2)
val <- rbind(c(-5,2), c(-3,1))
prob <- Problem(Minimize(max_entries(A, axis = 1)[2,1]), list(A == val))
result <- solve(prob)
result$value
