I would like to ask you a question about how to convert the output of solve function into matrix form. As far as I know, the output of solve function is structure. Here is my simple case;
syms x y
k(1,1)=x-6*y-15;
k(1,2)=x+4*y-6;
roots=solve(k==0)
The output is as follows;
roots =
x: [2x1 sym]
y: [2x1 sym]
I know I can call the roots by roots.x and roots.y. However, I will write parametric code with user defined number of equation. So, How can I store those roots into a matrix so that I can use for other operation?

Maybe better option is to use linsolve if the system of equations is linear. So that U'll obtain result as matrix. Also you can try smth like this.
c=struct2cell(roots.x);
m=cat(1,c{:});
disp(m);

Sophie, thank you for quick answer. The system of equations are nonlinear. However, your recommendation solved my problem. I changed only first row of your code. Thank you!
c=struct2cell(roots);
m=cat(1,c{:});
disp(m);
