[Num,Txt,Raw]=xlsread('MyData.xls');
x=Num(:,1);
y=Num(:,2);
z=Num(:,3);
contour(x,y,z);

Hi,
since contour expects a matrix I would do:
[Num,Txt,Raw]=xlsread('MyData.xls');
x=Num(:,1);
y=Num(:,2);
z=Num(:,3);
F = TriScatteredInterp(x,y,z)
[qx qy] = meshgrid(min(x):0.01:max(x),min(y):0.01:max(y))
qz = F(qx,qy);
contour(qx,qy,qz)
Maybe you have to make the steps bigger for the meshgrid command. This depends on the range of your x and y values.
