How to obtain surfaces below the 3d plots

    YStress = HMatrix(:,i+1) % second column in excel data
    ZHigh = zeros(size(HMatrix(:,i)))+AxzH(j) % j is just a scalar number for heights
    
    x=[XLoc;flip(XLoc)]  % plot points on graph with axis (x,y)
    y=[YStress ; flip(zeros(size(YStress)))] % plot points (x,0)
    z =[ZHigh;flip(ZHigh)] % heights 
    
    [X,Y] = meshgrid(0:2:160,0:0.1:16)
    IN =inpolygon(X,Y,x,y) % Create polygon with ploted points
    X(~IN)=[];  % remove points mesh grid points outside polygon from X
    Y(~IN) = []; % remove points mesh grid points outside polygon from Y
    Z = zeros(size(X))+AxzH(j) % create appropriate Z values hieghts
    
    X = reshape(X,[7,263]) % just a trial to make Z a matrix
    Y = reshape(Y,[7,263]) % just a trial to make Z a matrix
    Z = reshape(Z,[7,263]) % just a trial to make Z a matrix
    disp(size(X))
    disp(size(Y))
    disp(size(Z))
    
    sur = surface(X,Y,Z) % this works only if Z is a matrix
%    T = delaunay(X,Y);
%    trisurf(T,X,Y,Z)  % also tried Trisurf but error points are collinear
    shading interp
    
    pH= plot3(XLoc, YStress,ZHigh);
    pH.LineWidth = 2;
    plot3(X,Y,Z,'o') % gives perfect results

Hi Anmol thanks for the reply. But my problem is a bit different.

I have created these graps using a for loop.

My query is very similar to this

https://www.mathworks.com/matlabcentral/answers/14002-3d-surface-plot-with-only-vectors

I have X and Y vectors. I want to have a surface. Surf requires Z to be a matrix. If i use gridata Z will still be a vector. If i use Tri surf Then it gives points are collinear.

Is there any way to tackle ths problem and create surface.

Thanks,

Sanoop Siby
