MATLAB: How to remove invalid left hand side of assignment, invalid “=” usage might be invalid matlab syntax and invalid character(s) in the code? Because this is the final project so i need to submit this. Really need help please.the algorithm also attached.

MATLAB Runtime Server

Seeking help. how to remove errors in code?
please help me to solve this. thanks in advance
Mobile device set: \mathcal {N}=\{1,2,\cdots,N\};

  • With a whole bunch of speculation as to what the notation means:
    Mobile_device_set = 1..N;
    Transmission_prower_to_MBS = p_(1:N, M):
    Transmission_prower_to_SBS = p_(1:N, S);
    for i = 1 : N
    Computation_tasks_T_{i} = {d_(i), c_(i), t_(i,max)};
    Categorized_device_sets_G_L = [];
    Categorized_device_sets_G_O = [];
    Categorized_device_sets_G_R = [];
    for i = 1 : N
    t_(i,L) = c_(i) ./ f_(i,L); %local time
    e_(i,L) = c_(i) .* delta_(i,L); % local energy consumption
    if t_(i,L) > t_(i,max)
    Categorized_device_sets_G_R = union(Categorized_device_sets_G_R, i);
    elseif t_(i,L) <= t_(i,max)
    if (e_(i,L) < min\{p_{i}^{M}\left\lceil{n_{o}^{M}}\right \rceil ,p_{i}^{S}\left\lceil{n_{o}^{S}}}\right\rceil\ + c_{i}\delta^{R}) %I could not figure out how to translate this line
    Categorized_device_sets_G_L = union(Categorized_device_sets_G_L, i);
    Categorized_device_sets_G_O = union(Categorized_device_sets_G_O, i);
    Parts of this make no sense. For example the only time i\Rightarrow \ mathcal {G}_{O}; can be encountered is if some variables are NaN, since NaN is the only case on the reals where (A>B) and (A<=B) can both be false.
