help you fix your problem As the comment by @user630317 points out, for a 3D image, u should be a 3D vector. Also, the image is 'voxelized' i,e, discrete. Therefore x is a vector with integer entries and units as voxels (not mm). Elements of u may or may not be an integer but has units as voxels. If u has fractional elements than would would have to do interpolate the fractional shifts and would lose information. code :
I = randn(3,3,3);
u = [1.5,1,1];
I2 = imtranslate(I,u);

I wish this helpful for you I have a fixed sized array in Matlab. When I want to insert a new element I do the following: , I'm not sure I understand your question, but I think you mean this: code :
A = [ A(1:pos) newElem A((pos+1):end) ]
A = [ A(2:end) newElem ]

Any of those help Say you have a matrix A:n by m, you can choose two elements at random as following, code :
A=[2 7 8;5 4 6;8 3 11];%given array
[n m]=size(A);
x=2;%two different random elements
i=randperm(n,x)%row index for x elements
j=randperm(m,x)%column index for x elements
A(i(1),j(1)) %First random element
A(i(2),j(2)) %Second random element
i =
2 3
2 1
4
8

Normalize intensity of series of images to obtain constant intensity Matlab

this will help Try normalizing so that the mean is 0 and the variance is 1. This is a common technique for making intensity images invariant to illumination changes, provided they are of the same scene. If you recall from probability theory, this is performed by obtaining the Zscore:
