I have a 3D matrix A with dimensions 64x64x301 (x,y,z (say)). Now I can plot the 3D version along the z plane by using mesh(A(:,:,1)). However, I am unable to do the same along x and y planes. It gives the error "Z must be a matrix, not scalar or vector". Please help!

After some digging, problem solved. I figured I should share the solution here.
The index terms (xd,yd,zd) need to be 2-D.
[yd,zd]=meshgrid(lat,depth);
[xd,zd]=meshgrid(lon,depth);
slice(x,y,z,c,xd,yd,zd);
Hello Paulus,
I would try to work only in 2D: projecting the plane to a line in the XY plane. Also, project the points on the XY plane. Once done, the problem just simplifies in only one constraint:
- Defining y=mx+n the projected line on the XY plane and A(xa,ya) an arbitrary point containing the XY coordinates from the 3D mesh:
- If ya>y(xa)=mxa+n the point is on the 'left'
- If ya<y(xa)=mxa+n the point is on the 'right'
Also, you will need to include the point inside the line case and give it a value (left or right).
If you pass the data including the 3D mesh and the plane I could work on a code. I hope that this explanation helps.
