Hi everybody,
In my GUI I´m loading data and storing them into variables X and y. The a value is entered by user.It looks like that:
[FILENAME,PATHNAME]=uigetfile('*.txt')
loaddata=load(FILENAME)
if (a==1)
X = loaddata(:,1)
y = loaddata(:,2)
end
if (a==2)
X = loaddata(:,1:2)
y = loaddata(:,3)
end
...
But I would like to add an error message in case that user load the wrong data set if he set the value a is equal for example to 1. Do you guys have any idea ? TY for help
