I have the following two variables: x (it represent depth of a material from the surface), y (it represnt a variable which changes as the depth of the material increases)
x=[ 0 0.04 0.164 1 2 3 4 5 6 6.052 7 7.965 8 9 10 ]
y=[ 6201.67 8328.37 6201.67 3476.751 2432.011 1820.878 1387.272 1050.941 776.1486 763.13 543.7965 349.14 342.5326 165.0053 6.201674 ]
I have made a plot of y against y. However, it is required to made a color plot like varying color for y (based on its magnitude) as the depth increases ie. x. For high values of y a darker color which decreses as the value of y decreases. An example plot is attached below for illustration only. Please help me

It is a bit more complicated than simply using surf, since you don't have 2D data, just a vector. There are probably other ways to make this, but this is an easy one. If you want to label your axes, note that y is now in the z-direction.
x=[ 0 0.04 0.164 1 2 3 4 5 6 6.052 7 7.965 8 9 10 ] ;
y=[ 6201.67 8328.37 6201.67 3476.751 2432.011 1820.878 1387.272 1050.941 776.1486 763.13 543.7965 349.14 342.5326 165.0053 6.201674 ];
surf([x(:) x(:)],ones(numel(x),2),[y(:) y(:)],...
'EdgeColor','interp')
view(90,0)
xlabel('x')
zlabel('y')
