NOT ENOUGH INPUT ARGUMENTS

function  BPBMI_plot(Sex, LastName, loc_data)

Weight = loc_data(:,2);
Height = loc_data(:,3);
BP = loc_data(:,4);

%convert Height from centimeters to meters
Height = Height / 100 ;


% Calculate BMI
bmi = Weight / (Height).^2 ;


figure;
hold on
%plot data on left side
yyaxis left
%plot bmi
bar(bmi, 'W')
ylabel('BMI')
%plot data on right axis

%plot Blood Pressure
plot(BP, 'r-+');

%plot Weight

You might be running the function striaght away using f5 or hitting run button. You need to provide the inputs to the function and then call the function.

Sex = define your value ;
LastName = define your value ;
loc_data = define your value ;
% Now call the function 
BPBMI_plot(Sex, LastName, loc_data) ;

[Khaled Awda]

all these values was defined by using other scripts

[Walter Roberson]

But are you passing the values in? Inside of a function, Matlab will never look in the base workspace to see if a variable with the same name happens to be defined.

[Khaled Awda]

yes i am passing using a main script that connects all scripts together

[Khaled Awda]

with functions

[Walter Roberson]

Do you have a line of code that looks similar to

BPBMI_plot(Sex, LastName, loc_data) ;

? If you do, is it the only place you mention BPBMI_plot?

If the call is within a function is it possible that you are not passing all needed parameters to that function?

[Khaled Awda]

i have 4 different file

sex

lastname and loc_data

BPBMI

main - calls all functions in the same order

sex

lastname and loc_data

BPBMI

I suggest that you open a support case with Mathworks, as you are not able to share your code with us.
