template<typename L, typename A, typename B>
auto visit_measurement(A &¶m, B &&cov, size_t dim, L &&lambda)¶ Dispatch a lambda call on an overallocated parameter vector and covariance matrix, based on a runtime dimension value.
Inside the lambda call, the vector and matrix will have fixed dimensions, but will still point back to the originally given overallocated values.
Note
No requirements on
A
andB
are made, to enable a single overload for both const and non-const matrices/vectors.- Template Parameters
L – The lambda type
A – The parameter vector type
B – The covariance matrix type
- Parameters
param – The parameter vector
cov – The covariance matrix
dim – The actual dimension as a runtime value
lambda – The lambda to call with the statically sized subsets
-
template<typename L>
auto visit_measurement(size_t dim, L &&lambda)¶ Dispatch a generic lambda on a measurement dimension.
This overload doesn’t assume anything about what is needed inside the lambda, it communicates the dimension via an integral constant type
- Template Parameters
L – The generic lambda type to call
- Parameters
dim – The runtime dimension of the measurement
lambda – The generic lambda instance to call
- Returns
Returns the lambda return value
