In an attempt to solve 6 differential equations for the abundance of elements in the sun, each depending on a number of nuclear reactions, I have fount a 6X6 matrix equation of quantities Y and Y' (six of each). The individual equations can be solved with NDSolve with initial conditions and parameters found in tables. My question is how can we solve the six equations together by solving the matrix equation? It will appreciate if one can give me an example of 2X2 matrix, I will work out the generalization.
