max_entries function

Maximum

The maximum of an expression. methods

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.

Returns

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)
