How to pass a vector as an argument in vba function generated in MATLAB

Hi,

I have the following simplified version of my code:

function  [y_hf] =testfunction(y_lf,s)

n_hf=sum(s);

y_hf= [ zeros(n_hf,1) ; y_lf];

And that is what it is supposed to do:

>> y_lf=[1 2 3 4]';
>> s=[1 4 5 7]';
>> y_hf=testfunction(y_lf,s)

y_hf =

       0
       0
       0
       0
       0
       0
       0
       0
       0
       0
       0
       0
       0
       0
       0
       0
       0
       1
       2
       3
       4

Using the compiler toolbox I created an excel Add-In for this function.

The only way that I managed to make the function work in Excel VBA is by declaring the input arguments as 2-D arrays with 1 column and variable number of rows, such as the following example:

option explicit
Sub testme()

Dim s(5, 1) As Double
Dim y_lf(5, 1) As Double
Dim y_hf As Variant

s(1, 1) = 3
s(2, 1) = 4
s(3, 1) = 6
s(4, 1) = 3
s(5, 1) = 9

y_lf(1, 1) = 10
y_lf(2, 1) = 20
y_lf(3, 1) = 15
y_lf(4, 1) = 25
y_lf(5, 1) = 18

y_hf = testfunction(y_lf, s)

Range("A1").Resize(UBound(y_hf, 1), 1).Value = y_hf

End Sub

But what I want to have as arguments in the function are vectors, like the following:

Dim s(5) As Double
Dim y_lf(5) As Double

s(1) = 3
s(2) = 4
s(3) = 6
s(4) = 3
s(5) = 9

Dim y_hf As Variant

y_lf(1) = 10
y_lf(2) = 20
y_lf(3) = 15
y_lf(4) = 25
y_lf(5) = 18

This is the error I get as an output in the testFunction output:

Error in testfunction.Class1.1_0: Dimensions of matrices being concatenated are not consistent.

Thank you in advance for your help.
