Dear Uqlab :
Distinguished professors, students have many questions when using UQLab. If you can answer them in time, students will be grateful.
When I call uqlab with isight, the call window displays cross validation errors during program execution, but the error message displays that Copula cannot be recognized, resulting in no output.
Error:Action “Commands” execution failed: uq_copula_dimension (line 14) uq_copula_dimension: missing field Parameters given copula
INPUT: a0 h1 h2 m z
output： g1-g8 g11 g88
