I have read a paper about Dissipation-Induced Multicritical Phenomena, the relevant DOI is above.Its [21] reference is supplemental material,the sixth part gives a set of ten equations,and we want to gain its steady state, so the lhs is set to zero, thus,we obtain a ten-dimensional linear equtions.
How could i get this analytical result by Mathematic, you can download my notebook, help me solve this. Shall i think about block matrix?
