hi how can i evaluate the function below from x=1,x=2 into a step of 0.1 y=x/(x2+1)

1. Y=X/(X2+1)

[Manikanta Aditya]

You can do this:

x = 1:0.1:2; % Define the range of x with a step of 0.1
y = x./(x.^2 + 1); % Evaluate the function
disp(x)

    1.0000    1.1000    1.2000    1.3000    1.4000    1.5000    1.6000    1.7000    1.8000    1.9000    2.0000

disp(y)

    0.5000    0.4977    0.4918    0.4833    0.4730    0.4615    0.4494    0.4370    0.4245    0.4121    0.4000

x = 1:0.1:2; % Define the range of x with a step of 0.1
y = x./(x.^2 + 1); % Evaluate the function
plot(x,y)

syms x

y   = eval('x/(x^2 + 1)')   % <-- check if the function is correct

y = 

xa  = 1;                % start point of [xa ≤ x ≤ xb]
xb  = 2;                % final point of [xa ≤ x ≤ xb]
xs  = 0.1;              % step size
xval= xa:xs:xb          % values of x from xa to xb

xval = 1x11

1.0000 1.1000 1.2000 1.3000 1.4000 1.5000 1.6000 1.7000 1.8000 1.9000 2.0000

y   = subs(y, x, xval)  % substitute the values of 'xval' into 'x'

y = 

plot(xval, y, '-o'), grid on, xlabel x, ylabel y
