Index in position 2 exceeds array bounds (must not exceed 2171).

Dear members of this forum, ☺🙂🙏🏻😊☺

I hope and pray that you people will be good and happy....

I am receiving this error "Index in position 2 exceeds array bounds (must not exceed 2171)."... I append red-colored screenshot/snapshot of the received error and also the updated MATLAB code for convenience of the member who may become of help to me in this matter...

I scrolled through my MATLAB code several times but no success so far since few days...Therefore, I am posting here on this forum... Already I posted to one of my already going another query on this forum, MathWorks but response still awaited... Therefore, I had to post here also...

Relevant possible solution is requested... 😊☺😊🙂

Many thanks in advance

Index in position 2 exceeds array bounds. Index must not exceed 1865.

I don't understand how you came up with the calculation for ravailk, but the sum of all the sizes is leading to a number greater than the total number of columns (position 2) in x.

The result of this calculation is 100000816 while the total number of columns in x is indicated in the top of the error message (1865 here, but it appears to change every run).

floor(Numtk+size(ttransij,2)+ size(texeij,2)+ size(D_Cloud,2)+size(F_Cloud,2)+...
    size(MuRSU,2)+size(MaxNumtk,2)+size(E,2)+size(DPrc,2)+size(pc,2)+size(Muc,2)+...
    size(Mui,2)+size(Muk,2)+size(B,2)+size(pi)+size(pm,2)+size(W,2)+size(Wfog,2)+...
    size(t,2)+size(T,2)+size(cdk,2)+size(j,2)+size(i,2)+size(TasksperVehicle,2)+...
    size(NTotal,2)+size(Numv,2)+size(Numtk,2)+size(TijPrime,2)+size(loop1,2)+...
    size(Fprime,2)+size(PhikPrime,2)+size(D,2)+size(F,2)+Numv)

It is also interesting that the result is a 1x2 vector. It is probably supposed to be a scalar. You can fix that by replacing size(pi) with size(pi,2).
