function error in matlab app desinger

3 次查看(过去 30 天)
I tried to use app function as helper function in app desinger
but i got error that Illegal use of reserved keyword "methods".
this is the function
methods (Access = private)
function result=belladead(app,Rs,T,API);
a=10^(0.43+(8.33/API));
x1=(1.8*10^7)/(API^4.53);
x2=(360/(T-260))^a;
uod=(0.32+x1)*(x2);
result=uod;
end
end
this is the call back function
value = app.SelectCorrelationDropDown.Value;
Rs=app.RsSCFSTBEditField.Value;
T=app.TREditField.Value;
API=app.APIEditField.Value;
switch app.SelectCorrelationDropDown.Value
case 'Beal’s Correlation'
g=belladead(app,Rs,T,API);
app.uodcpEditField.Value=g;
case 'Glaso’s Correlation'
a=10.313*(log10(T-460))-36.447
uod1=(3.141*(10^10))*((T-460)^-3.444)*(log10(API))^a;
app.uodcpEditField.Value=uod1;
otherwise
disp("please select correlation")
end

Hi Abdulrahman,
I understand that you are getting the error 'Illegal use of reserved keyword "methods"' while writing a helper function.
There are two possible reasons for this error:
  1. You are not defining this method inside a class.
  2. You are defining this method inside of another method of the same class.
Thank you,
Rishav Saha
