You can execute Excel Macro functions from the MATLAB environment by using the ActiveX interface.
Here are two simple examples on how to call a Sub (in VB/VBA: a procedure without any returned values) and a Function (returns a value):
excelObject = actxserver('Excel.Application');
excelObject.Workbooks.Open('C:\Test.xls');
excelObject.Run('TestSub', 'Hello world');
retValue = excelObject.Run('TestFnc', 'Hello world from a function');
The Excel Macro routines that belong to this example (Test.xls) should be in a module and look as follows:
Public Sub TestSub(arg1 As String)
MsgBox arg1
End Sub
Public Function TestFnc(arg1 As String)
TestFnc = "Passed: " & arg1
End Function
