Hello lovely Mathworks members,
( I tried to find similar question but could not find any, so excuse me if there is already existing answer please share the link)
There is a 3D surface matrix which has some entries outside of a curve area and I want to remove the 3D matrix entries outside of a 2D curve. Can someone please help to understand how to remove the outside of curve entries of the 3D matrix. In attachmnet you will find both 2D and 3D matrices.
Best Regards!

You hvae to use inpolygon. Read about it.
load('3D_XYZ_Data.mat') ;
load('2D_RestrictedArea.mat') ;
X = XYZ_Data(:,1) ;
Y = XYZ_Data(:,2) ;
Z = XYZ_Data(:,3) ;
x = Restricted_Area(:,1) ;
y = Restricted_Area(:,2) ;
idx = inpolygon(X,Y,x,y) ; % get points lying inside the restricted points
plot3(X(idx),Y(idx),Z(idx),'.r')
hold on
plot(x,y,'.b')
