Re: [ferret_users] how to change the value of the variable in Ferret?
Hi Xia Changshui,
You can do that easily by using ferrets if-then logic. Try
let h_new=if (i ge 50 and i le 60 and j ge 50 and j le 60) then h + 0.5
else h
Just remember that you always need to define new variables because of
ferrets "delayed" evaluation.
More details are found in the ferret documentation
http://ferret.pmel.noaa.gov/Ferret/Documentation/Users_Guide/current/Chapter3_Variables_and_Expressions.htm#_VPINDEXENTRY_519
Cheers, Ingo

Dear all,
I have a simple qusetion, I have a netcdf format file, the variable in
it is H(100,100) , I want change the value H from i=50 to 60, j=50 to
60, how to achieve this?
in fortran it is very easy
for j=50,60
for i=50,60
h(i,j)=h(i,j)+5.0
enddo
enddo
but how in Ferret?
Thanks
