A scanned copy is usually stored on a computers memory after scanning and can be reproduced as you wish by only taking one digital imprint of the original document. A color copy, however is only a simple imprint (copy) of the original document which is not stored on a computers memory.
One way to invoke an Excel macro from MATLAB is by launching Excel as a COM server from MATLAB using the 'actxserver' command. Suppose there is an Excel file 'myFile.xls' containing the macro called 'Macro1'. The following commands should first open the Excel file and then run the macro: % Create object.
The name of the function-that is, how to call it in MATLAB-is determined by the name of the file containing the function. This method is good for functions of any complexity, since the file can contain a multitude of expressions, create local variables, and return as many variables as specified in the file.
