Viewing different planes from DICOM image slices

I have a 3D DICOM data (slices) and I need to display the three planes (axial, sagittal and coronal) from that data. I read all the slices in MATLAB and used that 3D matrix as follows.

Axial = dicomMatrix(:, :, zIndex);
Sagittal = dicomMatrix(xIndex, :, :)
Coronal = dicomMatrix(:, yIndex, :)

But when I display the above images the sagittal and coronal planes seems like exchanged. What am I doing wrong?

As far as my understanding, the orientation of DICOM images are, L->R, A->P & I->S Therefore I considered that X is increasing to R, Y is increasing to P and Z is increasing to S.

The problem is that the first dimension in MATLAB is y (rows) and the second is x (columns), not the other way around. See Matrix Indexing in MATLAB.
