How to run a loop

[Luisa Riascos]

HI i'm a new user in mata and i'm trying to run a loop but i got an error message that says 'expectedValueFunctionnCapitalnProductivity' found where almost anything else expected

Here's the code

while(maxDifference > tolerance){
for(nProductivity = 0; nProductivity < nGridProductivity; nProductivity++){
for(nCapital = 0; nCapital < nGridCapital; nCapital++){
expectedValueFunctionnCapitalnProductivity = 0.0;
}
}
else{
for(nProductivityNextPeriod = 0; nProductivityNextPeriod < nGridProductivity; nProductivityNextPeriod++){
expectedValueFunctionnCapitalnProductivity = mTransitionnProductivitynProductivityNextPeriod * mValueFunctionnCapitalnProductivityNextPeriod;
}
}
}

Can someone help me ?

Hi Luisa
I can't figure out what you are doing, but semicolons aren't necessary.
And there is an "else{" with out an if.
Indentions will make your code more readable.
And some of your variable names are too long for my taste.

I've tried to guess what you wanted below:

while(maxDifference > tolerance){
    for(nProductivity = 0; nProductivity < nGridProductivity; nProductivity++){
        for(nCapital = 0; nCapital < nGridCapital; nCapital++){
            expectedValueFunctionnCapitalnProductivity = 0.0
        }
    }
}
//else{
for(nProductivityNextPeriod = 0; nProductivityNextPeriod < nGridProductivity; nProductivityNextPeriod++){
    expectedValueFunctionnCapitalnProductivity = mTransitionnProductivitynProductivityNextPeriod * mValueFunctionnCapitalnProductivityNextPeriod
}

Thank you so much, I-m having tons of problems with the code, I think it was translated in a bad way.
By theh way, do you know how to declare an integer variable that will be used later.... for example nCapital is an entry of a 17820x5 matrix
