Using Matlab to drive Mathcad

I am trying to use Matlab to open a Mathcad sheet, pass data and save versions of the sheet with the inserted data.

So far I can open the Mathcad sheet, insert values but cannot alter definitions (when I save the sheet the values revert to their original uncalculated state - which is what they should do).

Does anyone know the code to set definitions in Mathcad via Matlab?

Any help would be much appreciated.

h = actxserver('Mathcad.Application')
h.visible=1     % make the application visible!
h.methods       % these are the methods that are available at this level
h.invoke        % these are the actions that can be invoked at this level
inspect(h)      % more investigation of the application inteface

h.worksheet.invoke      % One level down in the interface - the worksheet level
sht = h.worksheet.Open('C:\Users\gregory.kemble\Documents\MATLAB\test_mcad_sheet.mcd')     % open our MathCAD worksheet

sht.SetValue('in0',7)
sht.SetValue('in1',6)
sht.SetValue('var1',5)

sht.Save

fullname = 'C:\Users\gregory.kemble\Documents\MATLAB\new5.mcd' %sht.FullName

%new_sht = sht
sht.SaveAs(fullname)
sht.Close

h.Quit              % this causes the MathCAD application attached to handle 'h' to quit
h.delete

Hello, Could you provide the mathcad file ?

Thanks

would it make sense to consider focusing on MATLAB?

if not, it's probably because Mathcad has something that MATLAB doesn't?

what would it be, the 'hc' instead of 'L'?
