rb_test_convergence(detailed_data,model)

function determining the maximum and minimum test-error (linfty-l2 or estimator) for the given set of vectors mu (columns in detailed_data.RB_info.M_test) of the RB simulation with corresponding RB set. A convergence test is performed by performing this maximum and minimum detection for all numbers of RB from 1 to the complete set. the output is max_test_errs(i): the maximum test-quantity on the given mu-subset for reduced basis RB(:,1:i). The number of the mu, which incurs this maximum error is returned in max_mu_index(i). Similarly for min_test_errs and min_mu_index.

Parameters

detailed_data	detailed data
model	model

Return values

max_test_errs	max test errs
max_mu_index	max mu index
min_test_errs	min test errs
min_mu_index	min mu index

Required fields of model:

• RB_error_indicator —  error or estimator
• RB_detailed_test_savepath —  in case of error this path either contains the test-samples or they are generated.
• error_algorithm —  algorithm computing the true error in case of error mode
• test_N_samples —  (optional) number of N samples, which are tested, i.e. value 11 for a basis of size N=21 will give 11 test-results for the values N = 1,3,5,7,9,11,13,15,17,19,21 an equidistant sampling of the N-interval is realized. If not specified, all numbers 1:N are tested
• set_mu —  set mu

Required fields of detailed_data:

• RB_info.M_test —  RB info.M test
• RB —  RB
• grid —  a structure containing geometry information of a mesh used for the discretizations
