You will get a surface or a contour in this case. For example,
t=@(x,y)(x.^2-2*x-x.*y+2*y.^2);
x = -10:0.1:10; % define range and mesh of x and y which will be shown in figure
y = -10:0.1:10;
[X, Y] = meshgrid(x, y);
surf(X, Y, t(X,Y));
figure;
contourf(X, Y, t(X,Y));

t = 0:pi/50:10*pi; %% % Calculate sine for each value in t. st = sin(t); %% % Calculate cosine for each value in t. ct = cos(t); %% % Use the 'plot3' function to display a three-dimensional plot of a set of data points. figure; plot3(st, ct, t) xlabel('sin(t)') ylabel('cos(t)')
