The returned structure contains measured intensities, axes positions and other useful information — sample ID, comment, (hkl) indexes, radiation wavelength, etc. Scan intensities and relevant axes positions are stored in simple matrices.
The XRDMLread function is freely distributable under the Simplified BSD license. It utilizes a Matlab XML Parser XMLTree toolbox, which can be freely downloaded under the GPL license from the XMLTree website.
Loading XRDML data in Matlab is as simple as the single command below. The most interesting fields may be the measured intensities — d.data in cps and axes positions — d.Theta2 and d.Omega.
