Detailed Description

template<typename P>
class roboptim::trajectory::Freeze< P >

Freeze parameters by modifying argument bounds.

This helper class expects a vector of pairs (argument id, value) to freeze the given arguments to their associated value.

For instance, the vector: [(0, 5.), (3, -12.)] forces the first parameter to 5 and the fourth one to -12.

This modifies the argument bounds for each frozen parameter.


Member Typedef Documentation

template<typename P >
typedef std::pair<Function::size_type, Function::value_type> roboptim::trajectory::Freeze< P >::frozenArgument_t

Pair representing an argument index and a value.

template<typename P >
typedef std::vector<frozenArgument_t> roboptim::trajectory::Freeze< P >::frozenArguments_t

Vector of pairs (argument index, value).

This type defines which arguments to freeze and their associated values.

template<typename P >
typedef P roboptim::trajectory::Freeze< P >::problem_t

Problem type.
