Hi everyone,
There is a function in Matlab's netcdf toolbox, called "parent" which returns
the parent netcdf object. Is the any way I can get the functionality in Octcdf?
It's usage is as follows:
cdf=netcdf('example.nc');
Par=parent(cdf('longitude'))
close(cdf);
which returns:

Hi everyone.
locations = find(logical(good_var));
svar=var{i}(locations);
In the above code, 'logical' converts the elements of the array good_var into
logicals. 'find' returns indices that evaluate to TRUE. So now, locations
contain indices of non-zero elements of good_var.
In the next statem
Hi Alex.
The code given below gives the output (in matlab) as "longitude temp". That is,
"longitude" and "temp" are the variables which depend on the dimension
"longitude".
Could you please make necessary correction to the code below so that I can get
similar output in octave as well.

Could you please show that with an example.

Hi Stefan.
"bin" is not a file but a dimension on which other variables depend. It is
having 20 elements, from which I want to cutoff 10 elements so that "bin" then
has only 10 elements.
Below is a sample code, showing what function gives what error. Uncomment the
function and you will get the
Hi.
In a netcdf file, I have "bin" as one of the dimensions with length 20
elements. I want to reduce it to 10 elements. With matlab, this can be done
with:
B = nc('bin');
B=resize(B,10);
Could you please tell me, how that can be done in octave/octcdf.
Thanks,

Hi everyone.
The following code creates a netcdf file and then isempty checks if it is
empty. But though it is not empty, it shows the file as empty.
latitude = -90:1:90;
longitude = -179:1:180;
[y,x] = meshgrid(pi/180 * latitude,pi/180 * longitude);
temp = cos(2*x) .* cos(y);
nc = netcdf('exam
Hi all.
Is there any way to copy attributes from one netcdf file to another netcdf file?

Hi all.
There is a function 'var' in matlab's netcdf such that var(self) returns the
list of variables that contribute to self, a composite "ncvar" object.
Is there any such function in Octcdf or is there any alternate way from which I
can get the same functionality as 'var'.
Thanks.

Hi.
I don't know any theory part behind it. The only reason for that suggestion is
that, it makes my code (given below) work.
cdf = netcdf('glo_att.nc','c');
cdf('lon') = 6;
cdf('lat') = 4;
cdf{'var'} = ncchar('lon','lat');
cdf{'var'}.units = 'm';
close(cdf);
Thanks.

Hi.
I think I have got the bug. :)
In octcdf package in ov-ncvar.h instead of
octave_idx_type numel(const octave_value_list&)
{
return dims().numel();
};
it should be
octave_idx_type numel(const octave_value_list&)
{
return 1;
};
Thanks.

Hi.
A small correction to my previous mail. In stead of "nc{'var'}.units = 'm';"
I should have been using "cdf{'var'}.units = 'm';" as in
cdf = netcdf('glo_att.nc','c');
cdf('lon') = 6;
cdf('lat') = 4;
cdf{'var'} = ncchar('lon','lat');
cdf{'var'}.units = 'm';
which gives me (one error instead of
Hi.
I installed octcdf from svn. Now, for "nv.units = 'm';" I get

while for "nc{'var'}.units = 'm';" I get

Dear Sir.
In that case, what is the next step I should take to get rid of the error?

Hello Sir.

creates a netcdf variable of type ncchar, with netcdf dimensions 'lon' and

Executing these two statements also give the same error:

Hi everyone.
The statement
nc{'var'}.units = 'm';
was working fine in octave-3.2.3, but with octave-3.3.50+, it gives the
following error:
error: invalid assignment to cs-list outside multiple assignment.
Please help.
Thanks.

Hi all.
For "cdf=ncenddef(cdf)", I get the following error:

What am I supposed to do?

Installing libnc-dap-devel helped, but now I get this:

Hi Ron.
The description of libnc-dap says it is an alternative implementation of
Unidata's netCDF API.
I am already having libnetcdf installed.
Won't installing libnc-dap create conflict?
Thanks.

I am having Octave (3.2.3) with octcdf-1.0.13 on 64-bit x86_64 Redhat

Please refer the following octave code.

Hi everyone.
In Matlab, if the dimension's size is not known the following is used :

I wanted to know, what is the syntax to do the same in octcdf?
nc.('TIME') = ???
Thanks.
