How can access formulas as I process it with Matlab?

I load an xls file in Matlab, 开发者_如何学Pythonand I need not only the numeric values but the formulas also. Do you have any idea?

Look at this submission on File Exchange: AnalyseExcelFormulas

If you want to generate a formula from the data values in the xls file, perhaps the Curve Fitting Toolbox is what you need.
