GetVariable from function in visual basic script

Question

0 个投票

I am using the matlab automation server to call a function from a vb script

Result = Matlab.Execute("z=first([2 7],[1 5])") this is a function that ads the values of the 2 vectors and this works

Matlab.GetVariable("z","base") But when i try to get the variable from this function, i get the following error

error: cannot use quotation marks when calling a sub value

Does anybody knows what seems to be the problem with this? Or is not possible to get a variable from a function

thanks in advance

Hi,

when I do this it works fine:

       Set ml = CreateObject("MATLAB.application")
       ml.Execute ("z = rand(1)")
       Val = ml.GetVariable("z", "base")
       msgbox Val

Val then contains the value of z (choosed rand(1) to get one value only so that i can display it easily). What is your full code?

You were right, it does seem to work now

I place the output in C, but what datatype gives the Get.Variable standard? Because printing C in a txt file seems not to be possible

Look at the IDL signature:

HRESULT GetVariable([in] BSTR varname, [in] BSTR workspace, [out, retval] VARIANT* pdata)

It's a Variant. When you like to put some values into a file, i would do it from the MATLAB side because its more easy than doing it in VBS.
