I am stuck here since so long. Please help me.
For the following code:
Original "I" dimensions are 217x181x181
[nX,nY,nZ] = size(I);
[X,Y,Z] = meshgrid(1:nX,1:nY,1:nZ);
after Meshgrid X, Y, Z are of dimensions 181x217x181
Now from "I" how to find values in C matrix such that the dimensions of X, Y, Z matches with that of C.
For your case, you will want to use ndgrid instead of meshgrid, as this will give you matrices that are 217x181x181. You should take a look at the following for a good comparison of the two functions:
What is the difference between the NDGRID and MESHGRID functions in MATLAB?
To summarize:
NDGRID is to be used for higher dimensionality use and for when you want the results to reflect matrix/array notation:
MESHGRID is to be used for visualizing data and should be used primarily for when plotting two or three dimensional data.
