Recursive function + symbolic + function as parameter

Hello,

I am a new user of matlab. I am tring to convert my code from Mathematica. I want to compute this formula:

<<latex-codecogs-com-gif-latex--5Cdpi-7B200-7D-20-5Cnewline-20R_-7Bl-2Cu-7D-3DF_-7Bl-2C-5Calpha_-7B-28l-1-29-2Cu-7D-7D-5Cleft-20-28-20-5Csum_-7Bi-3D1-7D-5E-7BC-28l-1-29-7D-5Cleft-20-28-20-5Calpha_-7B-28l-1-29-2Ci-7DR_-7B-28l-1-29-2Ci-7D-20-5Cright-20-29-20-5Cright-20-29-20-5Cnewline-20R_-7B0-2Ck-7D.3DI_k>>

The I_k are Inputs (scalar), alphas must be symbolic variable (scalar) and Fs must be a function as parameter.

Now it is hard to implement that.

I am asking to the community for help.

What I explore: - symsum - the @ to pass function - sym/syms - recursive function

But after multiple days I did find a way do that.

The objectif is producing a function taking an array (all I_k) and array of all F this function should give me an array of the expression.

To implement that on Mathematica that take only 10 lines. The entering cost on Matlab are little bit higher than Mathematica. But I want to use different function doesn't exist on Mathematica.

Thanks

William

Additionnal information all l are from an array: [4 5 6] <= l_0 == 4 (so we have 4 I_k), l_1 == 5 and l_2 == 6 so the final result will be an array with 6 cells...
