Hi I want to plot a graph of Z=sin (x) cos(y) , y<3 and x>-3 but I'm unsure on how to code the range. Any help is much appreciated !

I understand that we usually assign a numerical value when assigning the range for x and y but I'm just unsure of how to process when it's x less than a certain value vs when x is equal or less than a value ( which I know how to do). Sorry if the explaination is confusing, I'm still new to matlab

Try this:

z = @(x,y) sin(x).*cos(y) .* ((x>-3) & (y<3));

[X,Y] = meshgrid(-5:0.5:5);

figure(1)
surf(X, Y, z(X,Y))
xlabel('\bfX')
ylabel('\bfY')
grid on
