ĭisp('Skipping variable with more than 3 dimensions') It's not exactly what you asked, but here's a script that writes all the. AFAIK, NetCDF3 and NetCDF4 formats do not have anything akin to Matlab's cell array, which can hold different types of data in each cell. Read the data in a variable into the MATLAB workspace. Neither, unfortunately, does Matlab currently (1/18) support the ability to read and write NetCDF4's variable-length strings (even though it has recently added a string datatype).Ĭonvert all numeric data to strings with sprintf(.). To read the data from NASA Space Physics Data Facility (SPDF) you are encouraged to use the CDF handling library from SPDF. The first variable contains CDF Epoch time values. This version of the library is provided for free and can be downloaded directly from SPDF. Move the MATLAB-CDF-Patch directory in the downloaded file to the directory you want the patch to be installed under. Refer to the CDF User's Guide for information about zModes. All CDF files opened this way have the zMode set to zModeon2. This function returns a CDF file identifier, cdfId. filename is a character vector or string scalar that identifies the file. The Installation instructions are fairly straightforward and there is little that can be added to it. cdfId cdflib.open(filename) opens an existing Common Data Format (CDF) file. The low-level interface returns these as double values. These will unfortunately have to be fixed length strings, which would need to be long enough to retain your necessary precision.ĭatatime cdflib.getVarRecordData (cdfid,0,0) datatime 6.3146e+13. cdfId cdflib.create (filename) Description cdfId cdflib.create (filename) creates a new CDF file with the name contained in filename. Then store the data as a fixed-length 2-D char array.Įncode your string data with numeric values. (Obviously, choose numeric values that cannot occur in your actual data.) This is similar to how you need to encode nan's, flagged by the attribute _FillValue.įor example, if you have strings of "Ozone", "CO2", "Methane", replace these with, say, -999, -998, and -997 respectively. 7.1K views 1 year ago This video describe the basics of a popular distribution and shows the coding, simulation for CDF (Cumulative Distribution Function) in matlab. You should also store the flags and corresponding original strings, either as attributes or as a separate array of chars and associated flag values.
