optimization - implementing quadratic programming in matlab -


i come across equation want solve in paper. (i'm not sure if can read public). minimizing equation 9 (see attached file) subject constraint in equation 10.

n 3-dimensional vector (so n can expressed px3 array), , c vector of length k (so c 1xk array). i' (a pxl array) , l (a 3xl array) both known. need find set of n , c.

the paper stated that:

'we used matlab implementation of trust region reflective quadratic programming optimization.'

i don't know how can done. not sure if refers quadprog or direct use of fmincon. in either case, have no idea how write objective equation , constraints equation in appropriate form function call. great if can show me how rewrite equation , use 'trust region reflective quadratic programming optimization', or provide other efficient ways solve equation.

thanks enter image description here

angularjs - ADAL JS Angular- WebAPI add a new role claim to the token -

i have created angular spa webapi backend using adal js authentication.as there no roles in ad, need manually add role claims in order give users access different api controllers. the roles stored in database. expecting inject claim through call webapi after authentication ad. webapi code might this. identity.addclaim(new claim("role", "user")); var ticket = new authenticationticket(identity, props); var accesstoken = startup.oauthbeareroptions.accesstokenformat.protect(ticket); is possible replace adal idtoken new token? is viable solution or there other better way handle this? as initial token generated azuread, possible edit token add new claim? appreciated. graph api supporting group claims. see here: http://justazure.com/azure-active-directory-part-4-group-claims/ if @ examples on page, users assigned groups , app can check group in claims. in current version of portal, need app manifest , modify it.
