How do I use NCWRITE to write an entire variable?

Hello, I'm working with netcdf file. I want to write a value to a variable that it's an array.

My problem is that when I do for example:

ncwrite('myfile.nc', 'variable', 2)

Value=2 of the variable. The value 2 only goes to the first position of the array variable, and what I want is to give the value 2 in all the components of the array variable.

How can I do it?

Update your third input argument to have the same size as the variable in the file that you are writing to.

For example, if your 'variable' in 'myfile.nc' is 20x30 elements, to set all the elements to the value 2 use:

ncwrite('myfile.nc','variable', 2*ones(20,30);

You can query the current size of the variable using ncinfo :

vinfo = ncinfo('t.nc','variable');
ncwrite('t.nc','variable', 2*ones(vinfo.Size));
