Array Declaration Problem ??
I am not clear what your code is doing, especially the ,,, my code ... bits,
but your array declaration is definitely wrong.
Try this
Function MyRoots(a, m As Integer, polish As String)
Dim a As Variant, Roots As Variant
Dim ad As Variant
Dim j As Integer, its As Integer
Dim x(2) As Double
ReDim a(m + 1, 2)
ReDim Roots(m, 2)
ReDim ad(m + 1, 2)
For j = 1 To m + 1
ad(j, 1) = a(j, 1)
ad(j, 2) = a(j, 2)
Next j
Call Laguer(ad, j, x, its)
Roots(j, 1) = x(1)
Roots(j, 2) = x(2)
MyRoots = Roots
End Function

Hello;
I'm trying to correctly pass the range B11:C14 to the Function MyRoots()
and
return the results by the array function to cells I11:J13.
Notice the use of ReDim. Declaring Dim a(m+1,2) As Double in Function
MyRoots() would produce a compile error: "Constant expresion required",
and
also I couldn't declare "a" as a 2D dynamic array!
I suspect the array variables declaration in the following example is the
problem.
The array Function MyRoots() incorrectly returns 0.0 results to cells
I11:J13.
cell B8::3
cell B9: myTrue
cells B11:C14 numerical values
cells I11:J13:: array function {=MyRoots(B11:C14, B8, B9)}
Function MyRoots (a, m As Integer, polish As String)
ReDim a(m + 1, 2) As Double
ReDim roots(m, 2) As Double
Dim j As Integer, its As Integer
Dim x(2) As Double
ReDim ad(m + 1, 2) As Double
......................................my code............
For j = 1 To m + 1
ad(j, 1) = a(j, 1)
ad(j, 2) = a(j, 2)
Next j
......................................my code............
Call Laguer (ad, j, x, its)
......................................my code............
roots(j, 1) = x(1)
roots(j, 2) = x(2)
......................................my code............
MyRoots = roots
End Function
Sub Laguer (a, m, x, its)
Dim x1(2) As Double
......................................my code............
x(1) = x1(1)
x(2) = x1(2)
......................................my code............
Exit Sub
End Sub
Your expert help would be greatly appreciated.
Regards.
