% Scalars can be computed directly as they appear in the expression, e.g.:
x=1; y=x^2+3/(x+1);
% For vectors or matrices, USE an elementwise operation (.), e.g.:
x=2:100; y=x.^2-3./(x+1);

You would use the same techniques that Image Analyst showed in replying to you at https://www.mathworks.com/matlabcentral/answers/1413242-how-to-solve-equation#answer_769277 -- just modify the function expression.
