Getting error about input argument

Hello! I'm working on my dataset, which contains 5955 images of 4 classes

For SMOTE, I tried the following code with input values

function allData_smote = mySMOTE ((5955,4); 5;('2552,227,621,2555'));

The result is an error

Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched

delimiters.

Error in barh (line 44)

h = bar(varargin{:});

Error in smote (line 22)

barh(sortedIDX);

Here is the SMOTE code

It looks like you are attempting to use the function mySMOTE() with your data by putting values into the definition of the function mySMOTE(). You shouldn't do that. Instead, restore the function definition to how it was originally:

function allData_smote = mySMOTE(allData, k,sortedIDX)

And then you can use the function mySMOTE() by calling it with your values as input arguments:

% Note: I'm not sure these are what you intended or whether the function
% mySMOTE() will run with these values, but this is how you call a function
your_allData = [5955,4];
your_k = 5;
your_sortedIdx = {'2552','227','621','2555'};

your_result = mySMOTE(your_allData,your_k,your_sortedIdx);

I found it to be really helpful, thanks a bunch!

The answer you gave me worked but I ended up with this error message

Out of memory. The likely cause is an infinite recursion within the program.

Error in mySMOTE (line 5)

your_result = mySMOTE(your_allData,your_k,your_sortedIdx);

I would appreciate it if you could help me again with this .Thanks

Oh, don't call mySMOTE() from within mySMOTE.m.

This part should be somewhere outside mySMOTE.m, like a separate m-file or on the command line:

% Note: I'm not sure these are what you intended or whether the function
% mySMOTE() will run with these values, but this is how you call a function
your_allData = [5955,4];
your_k = 5;
your_sortedIdx = {'2552','227','621','2555'};

your_result = mySMOTE(your_allData,your_k,your_sortedIdx);

Then your mySMOTE.m file will have the definition of the function mySMOTE like this:

function allData_smote = mySMOTE(allData, k,sortedIDX)
% function contents go here, exactly as they were when you downloaded it
end

Thank you for giving me the feedback and for your assistance!
