Singularity is very important thing of robust control.
Try to plot singular values over frequency of a MIMO system.
Test Suite of assert(isequal(singular_value_of(x),sigma)); is non-functional. x is undefined. sigma lacks parameters or an assigned value. Is the quesiton what function to use? Then use strcmp(funct_singularity,'sigma')
Borrowed from master Alfonso...
Without sigma OK, but without x ?
hint: I learned this trick from FrequencyDomain by studying the testsuite in the get_me v4 problem (http://www.mathworks.com/matlabcentral/cody/problems/1752-get-me-v4-cody-hacking-challenge), there is a very specific protection there against the hack needed to solve the 'x' issue here...
Thank you for this hint. It's obvious that the get_me v4 problem frustrates me.
