Help Calling a Function
显示 更早的评论
The following is my .m file. I have the reaeration function working fine. It is just the deOxygen function that will not work. I get the following error when trying to run the program: "Warning: File: myHW7.m Line: 21 Column: 24 Function with duplicate name "deOxygen" cannot be called."
Any suggestions? Thanks in advance Alex
function constant = reaeration(array)
function resultarray = deOxygen(array , constant)
load PollutionData.txt;
array = PollutionData(:,1);
timearray = (0:.5:250);
constant = reaeration(array)
resultarray = deOxygen(array , constant)
return
function constant = reaeration(array)
constant = ((array(5,:) .* array(3,:)) .^ 0.5) ./ (array(4,:) .^ 1.5);
return
function resultarray = deOxygen(array , constant)
array(3,:) = array(3,:) .* 0.001076; %conversion
array(6,:) = array(6,:) .* 0.0002778; %conversion
for i = 250: 0.5: 0, do, end
resultarray = (((array(6,:) .* array(2,:)) ./ (constant - array(6,:)) .* (exp(-array(6,:) * i * 3600) - exp(-constant .* i .* 3600)) + (array(1,:) * exp(-constant .* i .* 3600))));
return

You can't start out myHW7.m with these lines:
function constant = reaeration(array)
function resultarray = deOxygen(array , constant)
Those are function definitions which you define later in the m-file. So you're basically doing it twice and the first time you define them there's not even any body to the function. So, I assume you just want to call them, but to call them you need a function line with myHW7 in it:
function myHW7()
load PollutionData.txt;
array = PollutionData(:,1);
timearray = (0:.5:250);
% Now call (not define) the functions
constant = reaeration(array)
resultarray = deOxygen(array , constant)
return
% Now define other functions like reaeration() and deOxygen()
