variable dimension change nc file

I have downloaded era specific humidity data in .nc file.In that data specific humidity as a variable is present ant that is 4x3x4x9862 where 4=lon,3=lat,4=pressure level and 9862=time.Now I am creating a nc file where I want this in format 3x4x4x9862 where 3=lat,4=lon,4=pressure level and 9862=time. I have written a programme and create variable for nc file like that
nccreate('test_files.nc','q','Dimensions',{'lat' 3 'lon' 4 'lev' 4 'time' 9862 });
ncwrite('test2_files.nc','q',q(3,4,4,9862));
but
error Attempted to access q(3,4,4,9862); index out of bounds because
size(q)=[4,3,4,9862].
How can I solve the problem?

It works here on R2016a. Note that the filename is not the same in the two lines of code.

Try:
nccreate('test2_files.nc','q','Dimensions',{'lat' 3 'lon' 4 'lev' 4 'time' 9862 });
ncwrite('test2_files.nc','q',q);

ncwrite('test_files.nc','q',Q1);

ncwrite('test2_files.nc','q',q(3,4,4,9862));
This is working fine in my version 2017.

I have worked on matlab2015.ncwrite('test2_files.nc','q',q(3,4,4,9862)); giving error message.

In that case..write a matrix in loop.....write q(:,:,:,i) at a loop i.
