how do you solve

when x=1, y=x.^2+3 /(x+1)

and

when x=2:100, y=x.^2-3 /(x+1)

how do you solve this in matlab using vectorization method

Answer 1

[Sulaymon Eshkabilov]

% 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);

[Walter Roberson]

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.
