thanks for your answer,I know that it is better to write my own code, but I can modify an already one. I checked the paper of Uryasev, and I think that it is difficult to introduce the auxiliary variable as a vector. I used to use a fmincon solver, but I think that it should be better to use the linear programmation; that's why I need a code to modify it.Thanks
