Index exceeds the number of array elements. Index must not exceed 1.
Error in LE_RF_a (line 5)

fde12 only work on 3 dimensional? if you want to work on 4 dimensional where i have to change

Hi Rohini,
I understand that you are facing issue when working on 4-dimensional vector as input argument in ‘FDE12.m’.
I have debugged the code and found that while using 4 dimensions, in 'LE_RF_a.m' you are accessing 5th 6th 7th elements etc which is the cause of error, as shown below:
Also refer to line 114 in 'FDE12', it should be like shown below as y0 is a row vector
f_temp = f_vectorfield(t0,y0(1,:),Probl) ;
instead of
f_temp = f_vectorfield(t0,y0(:,1),Probl) ;
Hope it helps,
Regards,
Neelanshu
