How to fix: Attempt to execute SCRIPT fprintf as a function:

This is the script I've put in:

% The program calculates the volume of the water in the water tower.
h=input('Please enter the height of the float in meter ');
if h > 33
    disp('ERROR. The hight cannot be larger than 33 m. ')
elseif h < 0
    disp('ERROR. The height cannot be a negative number. ')
elseif h <= 19
    v = pi*12.5^2*h;
    fprintf('The volume of the water is %7.3f, cubic meter.\n',v)
else
    rh=12.5+10.5*(h-19)/14;
    v=pi*12.5^2*19+pi*(h-19)*(12.5^2+12.5*rh+rh^2)/3;
    fprintf('The volume of the water is %7.3f, cubic meter.\n',v)
end

Here's the error msg:

Attempt to execute SCRIPT fprintf as a function:
C:\Users\Holland\Desktop\MatlabExcel\fprintf.m

Error in Problem6Example3 (line 9)
    fprintf('The volume of the water is %7.3f, cubic meter.\n',v)

*I've struggled on this for a few hours now, any help would be much appreciated.*

Answer 1

[Fangjun Jiang]

fprintf() is a built-in function. \toolbox\matlab\iofun\fprintf.m is a help text file.

Why do you have your own C:\Users\Holland\Desktop\MatlabExcel\fprintf.m file?

It sounds like your fprintf.m is an M-script (without function keyword at the first line) but you are trying to use it as a function.

I was uploading data into that way and didn't change the pathway afterwards (no good reason).

Thanks for the help, I really appreciate it.
