i have tow matrix 3d need to find rmse(root mean squre error) and single to noise SNR between this tow matrix first muste be tow matrix have same dimention how can resize matrix 3d from 128*100*360 to 64*64*64
MATLAB: How can i use function imresize(a,[x y ]) (this function of 2D),with matrix 3D [x y z]

That can be straightforward or slightly complicated, depending on how you want to do it.
To extract the first 67 rows:
M = rand(128, 64, 1140); % Create Matrix (To Test Code)
Out = M(1:67,:,:);To interpolate across the rows:
D1 = linspace(1, 128, 67);Out = interp1((1:128), M, D1);Both will produce the matrix you requested, however they are not the same.

Hi,
Following code may help,
clcclose allclearn = 10;rmax = 10;x = linspace(-rmax,rmax,n);y = linspace(-rmax,rmax,n);z = linspace(-rmax,rmax,n);[X,Y,Z] = meshgrid(x,y,z);V = X.^2 + Y.^2 + Z.^2zslice=0;yslice=[];xslice=[];hslice=slice(X,Y,Z,V,xslice,yslice,zslice);rotate(hslice,[0 1 0],-45);view([1 1]);figureisosurface(V);hold on hslice=slice(X,Y,Z,V,xslice,yslice,zslice);rotate(hslice,[0 1 0],-45);Output:
