x = linspace(-10,10 ,51)'; y = linspace(0,0.3,51)'; [X, Y] = meshgrid(x, y); Z=X/(1+Y); surf(X, Y, Z); ylabel('t'); xlabel('x'); zlabel('u(x,t)').this is showing error .Now I want to know that the z=f(x)/g(x) why the code is not running

x = linspace(-10,10 ,51)';
y = linspace(0,0.3,51)';
[X, Y] = meshgrid(x, y);
Z=x/(1+y);
surf(X, Y, Z);
ylabel('t');
xlabel('x');
zlabel('u(x,t)')
It is showing error that matrix is singular and graph display is balnk. What is mistake with this code.Here in place of X it should be x is it so.
%%%%%%%%%%%%%%%%
Problem : What is wrong in this code
x = linspace(0,1 ,51)';
y = linspace(0,1,51)';
[X, Y] = meshgrid(x, y);
Z=exp(-4.*(pi^2)*0.5*Y)*sin(2*pi*X);
surf(X, Y, Z);
ylabel('t');
xlabel('x');
zlabel('u(x,t)')
Its not showing correct graph
