How to display output in a loop?

Hello,

I am doing this function . I cannot figure out how to display my output in how it is required. I have tried 'display' and fprintf. The code is correct(hopefully) becuase they gave us a flow diagram with what the code should be. I can attach later but i dont know how to get the display function to work in the loop and output in this format. I also need to add a plot of efficiency vs load.

%Declare Variables and Values

kVA=10000
Vp = 10
f = 60
Psc=204
Poc=133
Vsc=95
Isc=4.54
pf = -0.85

%Calculate rated Current


IR=kVA/Vp

%Calculate REQp 
REQp=Psc/Isc^2

%Load Matrix is in percentage
NSTEP = [120:-5:0]

if NSTEP>=0

    %
%Calculate total losses
Ploss=Psc + Poc

%Obtain Input PowerCalculate Pout
Pout=kVA*(NSTEP/(100*pf))

%Calculate PSC @ each load
Pscl=Psc.*((NSTEP/100).^2)

Pin = Ploss + Pout

%Calculate efficiency
n = (Pout/Pin)*100

fprintf (Pout,Pin,Ploss,Pscl,Poc,n)

else
    %Calculate for Maximum efficiency
    
    I = sqrt(Poc/REQp)
    
    %Calculate maximum efficiency
    nmax = ((Vp*I*pf*100)/(Vp*I*pf+Poc+Psc))
    
    %display max efficiency
    
    display('nmax')
    
end

Hi, you can use the function disp() to display the variables in the command window. Also, I have made some changes in your code. Refer to the below code to see whether it is giving the expected output.

clear; clc;
% Declare Variables and Values
kVA = 10000;
Vp = 10;
f = 60;
Psc = 204;
Poc = 133;
Vsc = 95;
Isc = 4.54;
pf = -0.85;
% Calculate rated Current
IR = kVA/Vp;
% Calculate REQp
REQp = Psc/(Isc^2);
% Load Matrix is in percentage
NSTEP = 120:-5:0;
% Indexing variable
% i = 1;
for i=1:1:numel(NSTEP)
    % Calculate total losses
    Ploss(i) = Psc + Poc;
    % Obtain Input PowerCalculate Pout
    Pout(i) = kVA*(NSTEP(i)/(100*pf));
    % Calculate PSC @ each load
    Pscl(i) = Psc.*((NSTEP(i)/100).^2);
    Pin(i) = Ploss(i) + Pout(i);
    % Calculate efficiency
    n(i) = (Pout/Pin)*100;
end
Poc_disp(1:25)=Poc;
% Store every variable inside a table
T = table(NSTEP',Pout',Pin',Ploss',Pscl',Poc_disp',n','VariableNames',{'LOAD','P_out','P_in','P_loss','P_scl','P_oc','efficiency'});
% Calculate for Maximum efficiency
I = sqrt(Poc/REQp);
% Calculate maximum efficiency
nmax = ((Vp*I*pf*100)/(Vp*I*pf+Poc+Psc));
% Display values
disp('OUTPUT'); disp(T);
disp(['Maximum Efficiency = ',num2str(nmax)]);

Hope this helps!
