Is there a way to trace the execution times of blocks and/or lines of code when using xPC? I want to find out how well my model is executing and while the TET metrics are useful, I really want to find out where the bottlenecks are in my code. ... 6 Jul 2010 13:22

Equispaced Vector Error
Hi! This has probably been asked several time however I couldn't find a post about it. I need to check whether an input array is equispaced. However x = 0.01:0.1:0.51; d = x(2:end) - x(1:end-1); won't result in a single valued unique(x) because of numerical errors. What is the best way to tackle this problem? ... 8 Jul 2010 03:43

Diff bet statement coverage and desicion coverage
Hi all, I want to know what is the difference between statement coverage and desicion coverage in generating code using Targetlink? I found one difference is in desicion coverage the code generator generates empty else paths for all if conditions unnecessraily irrespect of the model.
