MOSEK version 7.0.0.90 is now available for download. The major bug fixes are

• Fixed a bug on the OSX platform that caused problems when using the optimization toolbox for MATLAB.
• Fixed a bug in the mixed integer optimizer.
• Fixed a bug on the OSX platform that caused problems loading the MOSEK shared object.
• Fixed a bug that triggered an assert for certain semidefinite problems.
• Improved the documentation.

Investigating the data of a semidefinite optimization problem

In the MOSEK optimizer API it is not possible to dump a semidefinite optimization problem to a text file unfortunately. However, it is possible to dump the problem to a task file and then viewing the barA matrix using the following Python script.

import sys

import mosek

env = mosek.Env()

subi = num*[0]
subj = num*[0]
subl = num*[0]
subk = num*[0]
valijkl = num*[0.0]
