NCSOStools

NCSOStools is an open source MATLAB toolbox for

• symbolic computation with polynomials in noncommuting variables;
• constructing and solving sum of hermitian squares (with commutators) programs for polynomials in noncommuting variables.

It can be used in combination with semidefinite programming software, such as SeDuMi, SDPA-M or SDPT3 to solve these constructed programs.
