# structure similar to Matlab Cells

Hi I'm quite new in SAGE, I'm trying to learn it to migrate from Matlab. The problem I'm having is with Matlab cell structures, I couldn't find any similar structure in SAGE. The Matlab cells allows me to gather data of different sizes and styles in a single structure (matrices of different sizes for example) which I find really useful since my measurement data tends to change in size, headers, etc. Any feedback will be appreciated.
