MATLAB: Error when calling a previously made function in a separate script. Any ideas

calling another function

I keep getting an Error when calling a previously made function that was made in a separate script, even when it is on my path. This piece of code performs a multiple regression iterative search task with 3 parameters.

Here is the original function that gets called later(Both original function script and the other Script it is being called in are attached) I created the function that is being called myself.

Open each attachment separately and run iterative search script to see error.

The problem is caused by this line

WR = table(RedBloodCellCount,MeanWBCM30,'variablenames',{'RedBloodCellCount','MeanWBCM30'});% 2 previosly defined varibles are put into a table.

The function MultipleRegression require tables with field WhiteBloodCellCount and RedBloodCellCount, which the table WR does not contain. Change the 2nd variable name to WhiteBloodCellCount and it will give no syntax error.

WR = table(RedBloodCellCount,MeanWBCM30,'variablenames',{'RedBloodCellCount','WhiteBloodCellCount'});% 2 previosly defined varibles are put into a table.

*** "the following passage is just a suggestion based on observing your code, you may ignore it if you are sure about what you are doing."

It appears that you are making a logical mistake in your code. The new table WR contain the same value for WhiteBloodCellCount, so it might not be a good way to evaluate the performance of [Bestparams1, Bestparams2, Bestparams3]. It might be better to compare the parameters based on the original Data table as follow

Curve = MultipleRegression([Bestparams1,Bestparams2,Bestparams3], Data);

Also as I mentioned in Answer to your previous question, the line

SSD = A(:,3)-SimulatedY.^2; %calculate squared deviations at each data point in column 3 of data table (the row labelled IQ). Column 3 represents Y values.

is definitely wrong which is also indicated by your comment after the line. The correct is

SSD = (A(:,3)-SimulatedY).^2;

Hope this will help.

your last line of code should be

 a =linspace(min(A(:,2)), max(A(:,2)),30);

you had a colon separating min(A(:,2)) and max(A(:,2)) you need a comma

"SO I HAVE this ui table i want to select sujects and push 'submit' to calculate the sum of credit for the subject i selected"

In the callback function for the "submit" button, add this section of cose. You'll need to adapt it to your gui. That means you'll need to change the variable names and the column numbers.

% I create a fake UI table just for the example
h.uitable = uitable('Data', [{false;true;true;false;false},num2cell((1:5)')], 'ColumnEdit', [true, true],'ColumnName', {'Select','Credit'});
% In my table, the check boxes are in column 1, then credits are in column 2. 
% * you'll need to adapt this to your table (the variable names and column  numbers)
% * These steps could be combined into 1 line but it's more intuitive this way
% Step 1) Determine which rows have checked boxes
rowChecked = [h.uitable.Data{:,1}]';
% Step 2) Get the credits for each row of checked boxes
credits = [h.uitable.Data{rowChecked,2}]';
% Step 3) add the credits
creditSum = sum(credits);

"and after that i want to push a clear' button to reset all"

In the callback function to you "clear" button, add this section of code. Again, you'll need to adapt it to your GUI.

% set all checkboxes to false
h.uitable.Data(:,1) = {false}; 
% Remove all credits
h.uitable.Data(:,2) = [];
