    When anaysing data I need to create a 3×3 matrix for every timestep (N) (every timestep has it’s own unique 3×3 matrix)

    The matrix should have the following form
    Matrix = [1 to 3, 1 to 3, 1 to N]

    So for N=1 I have
    [A11_1 A12_1 A13_1
    A21_1 A22_1 A23_1
    A31_1 A32_1 A33_1]

    For N=2 the matrix contains:
    [A11_2 A12_2 A13_2
    A21_2 A22_2 A23_2
    A31_2 A32_2 A33_2]

    This function would be similar to the matlab function Matrix(1:3,1:3,1:N)=0

    You could solve this problem with two formulas. The first formula is a user-defined FPScript function and the second formula returns a list. Please see more details in the FlexPro help.

    Formula Matrix:

    
    Arguments n
    {(3,1,1), (3,1,1), (3,1,(n-1)/2.)}
    

    Formula ListResult

    
    Dim timestamp = {3,6,9}
    Dim result 
    For Each Row i In timestamp Do
       result := [timestamp, Matrix(Timestamp)]
    End
    result
