MATLAB: How to solve this error “Not enough input arguments.”

argumentsMATLABvariable

Dear all,

I have this code, though, I have previously defined all the variables, it still persist a message:

Not enough input arguments.
Error in Riesgo_C (line 2)
aux1 = V_in(V_in(:,12) == BATT,:);

The function:

function [deltaSOC] = Riesgo_C(V_in,BATT,PV,IRR)
aux1 = V_in(V_in(:,12) == BATT,:);
aux2 = aux1(aux1(:,11) == PV,:);
auxD = aux2(:,[2;4;6;8;10]);
auxI = aux2(:,[1;3;5;7;9]);
p = polyfit(auxI(1,:),auxD(1,:),1);
deltaSOC = polyval(p,IRR);
end

Best Answer

Your function requires 4 input arguments. You must have called it with less than 4 input arguments. Please check your code where you call the Riesgo function to make sure that you in fact have 4 input arguments. If you can not find the mistake, then please copy the exact code where you call the function and post it here.

MATLAB: For loop preallocation warning

Here is a general way.

If you use the following codes, you will get a warnings

x = []
for i = 1:10
    x(i) = sin(i); % sin(i) used as example

end
% or
x = []
for i = 1:10
    x = [x sin(i)]
end

You can solve the warning by pre-allocating and use indexing to assign elements

x = zeros(1, 10)
for i = 1:10
    x(i) = sin(i); % sin(i) used as example
end

For your code, following will work

%To simulate the 12 months at one click
current_path = pwd;
tic
load DATA_HILL.mat
PV_MAX_=zeros(12,1);
DEV_PV_=zeros(12,1);
SOC_=zeros(12,1);
month_=zeros(12,1);
PV_irr_=zeros(12,1);
Dev_2_=zeros(12,1);
z=zeros(12,6);
for month_number=1:12
    
    sim('HILL_V2.slx')
    disp(month_number);
    
    bdclose('HILL_V2.slx');
    
    %%%%%%
    %%%%Data upload
    load Power_PV.mat
    load SOC.mat
    load month
    load Irr
    %%%Results format

    %%%%Variables analysed in this study case
    PV_MAX=max(Power_PV);
    %

    DEV_PV= (PV_MAX/189000)*100;
    %
    SOC= min(SOC);
    m=mean(month);
    PV_irr=max(Irr)*189;
    Dev_2=(1-(PV_MAX/PV_irr))*100;
    
    % % % % All of the accumulated variables in the for loop
    PV_MAX_(i)=PV_MAX
    DEV_PV_(i)=DEV_PV;
    SOC_(i)=SOC;
    month_(i)=m;
    PV_irr_(i)=PV_irr;
    Dev_2_(i)=Dev_2;
    
    cd(current_path);
end
A=flip([month_ SOC_ PV_MAX_ DEV_PV_ PV_irr_ Dev_2_].*z);
%%%%To creat a table in order to represent the results of the simulation

Porque esta es el caso universitato, depende el medio del campus (por ejemplo, "dos campus" es uno/dos universitades) y depende tu licensia, contacta el servicio al cliente.
