Hi,
It is my understanding that, you want to know why you are getting empty syms of 0-by-1 as output when solving above system of equations.
To find a numeric solution, you must give same number of equations as the number of variables in input to 'solve' function.
In this line of code:
s = solve(eqn{1},eqn{2},eqn{3},eqn{4},eqn{5},eqn{6}, alfa, bta, gama, v1_3, v2_3, v3_3, a)
write the inputs to the ‘solve’ function as an array of equations and an array of variables, like this:
s = solve([eqn{1},eqn{2},eqn{3},eqn{4},eqn{5},eqn{6}, eqn{7}], [alfa, bta, gama, v1_3, v2_3, v3_3, a])
After correcting above syntax also you might face the same issue because, the solver returns an empty solution of 0-by-1 syms when no solutions exist for that system of equations.
For more information on this, refer following documentation:
Hope this helps!
