What is parseSolution and struct?

Hello I trying to know some code.

model.Plants.PZ{1}={[210 240],[350 380]};

model.Plants.PZ{2}={[90 110],[140 160]};

model.Plants.PZ{3}={[150 170],[210 240]};

model.Plants.PZ{4}={[80 90],[110 120]};

model.Plants.PZ{5}={[90 110],[140 150]};

model.Plants.PZ{6}={[75 85],[100 105]};

PZ = model.Plants.PZ;

nPlant = 6

for i = 1:nPlant

for j = 1:numel(PZ{i})

.....

I have a few questions.

1. what is ParseSolution ? Anybody know?

2. the model.Plants.PZ code

>> PZ = model.Plants.PZ

PZ =

1x6 cell array

{1×2 cell} {1×2 cell} {1×2 cell} {1×2 cell} {1×2 cell} {1×2 cell} why this result didn't respond that numbers (210 240 ,350 380 etc)?

3. How do I know numel(PZ{i})?

I tried to calculate. but

this

Error using numel

Bad subscribing index.

PLEASE HELP ME

1. Not sure what ParseSoultion is.

2. PZ is a 1x6 cell array where each cell contains 1x2 cell array, which ultimately contains the arrays. You can access the arrays like

PZ{1}{1} % 210   240
PZ{1}{2} % 350   380

PZ{2}{1} % 90   110
PZ{2}{2} % 140   160

3. The follwing code executes without any error

model.Plants.PZ{1}={[210 240],[350 380]};
model.Plants.PZ{2}={[90 110],[140 160]};
model.Plants.PZ{3}={[150 170],[210 240]};
model.Plants.PZ{4}={[80 90],[110 120]};
model.Plants.PZ{5}={[90 110],[140 150]};
model.Plants.PZ{6}={[75 85],[100 105]};
PZ = model.Plants.PZ;
nPlant = 6;
for i = 1:nPlant
    for j = 1:numel(PZ{i})
        disp(PZ{i}{j})
    end
end

% Display looks like
   210   240
   350   380
    90   110
   140   160
   150   170
   210   240
    80    90
   110   120
    90   110
   140   150
    75    85
   100   105
