How do read data form database row by row using for loop?(or without for loop)

Hi folks, I am trying to read files from data one row at a time because I have multiple equations which needs to be calculated and at the end, I am using linprog fuction to find minimum value. It doesn't start linprog function because mine Qg*t variable is written in matrix form. I want it to read one row at a time so I could find my solutions.

clc

clear all

Y = csvread('Podaci_Tea.dat'); %ucitava podatke iz zakulinih podataka

Qhc = Y (:,1).*1000*1000;%Jh , potrebna energija za grijanje u jednom satu, mnozim s jos 1000 jer tocku matlab cita kao decimalnu

N = 23; %broj VK

Qg = Qhc/3600;

t = 3600; %vrijeme

Tz1 = 20; %°C

Tw1g = 50; %°C

Tw1h = 7; %°C

cpz = 1050; %J/kgK

cpw = 4187; %J/kgK

roz = 1.225; %kg/m3

row = 997; %kg/m3

Vw = 488 / 3600 ; %L/s protok vode

Cmax = row * Vw * cpw / 1000;

kA = [99.9084 162.075 248.4162]; %W/m2K

Vz = [ 380/3600 430/3600 510/3600 ]; %m3/s

Pvent = [ 11.99605 17.38172 29 ]; %W

Cmin = roz .* Vz .* cpz; %W/K

NTU = kA ./ Cmin;

C = Cmin ./ Cmax;

eta = NTU .^ (-0.22);

epsilon = 1 - exp((1./(C.*eta).*(exp(-NTU.*C.*eta)-1)));

if Qhc > 0

Q = Cmin .* epsilon .* (Tw1g - Tz1);

elseif Qhc < 0

Q = Cmin .* epsilon .* (Tz1 - Tw1h);

else

Q=[0,0,0];

end

Q1 =Q(1,1);

Q2 =Q(1,2);

Q3 =Q(1,3);

A = [1 1 1; Q1*N Q2*N Q3*N];

b = [t; Qg*t];

a1 = A(1,:);

a2 = A(2,:);

x = linprog(Pvent', a1, t, a2, Qg*t, zeros(3,1), t * ones(3,1));%vrijeme rada ventilokonvektora u jednom satu

E = Pvent * x; %energija u jednom satu potrosena

for data you can use 116.53, 150.25, 180.35, 0

It doesn't matter so much, if it works on these numbers it will work on my file too.
