cdflib.hyperPutVarData

Write hyperslab of data to variable

Syntax

cdflib.hyperPutVarData(cdfId,varNum,recSpec,dimSpec,data)

Description

cdflib.hyperPutVarData(cdfId,varNum,recSpec,dimSpec,data) writes a hyperslab of data to a variable in a Common Data Format (CDF) file. Hyper access allows more than one value to be read from or written to a variable with a single call to the CDF library.

Input Arguments

cdfId

Identifier of a CDF file, returned by a call to cdflib.create or cdflib.open.

varNum

Specifies the variable containing the datum.

recSpec

Three-element array described by [RSTART RCOUNT RSTRIDE], where RSTART, RCOUNT, and RSTRIDE are scalar values giving the start, number of records, and sampling interval (or stride) between records. Record indices are zero-based.

dimSpec

Three-element cell array described by {DSTART DCOUNT DSTRIDE}, where DSTART, DCOUNT, and DSTRIDE are n-element vectors that describe the start, number of values along each dimension, and sampling interval along each dimension. If the hyperslab has zero dimensions, you can omit this parameter. Dimension indices are zero-based.

data

Data to write to the variable.

Examples

Create a CDF, create a variable, and then write a slab of data to the variable. To run this example, you must be in a writable folder.

cdfid = cdflib.create('your_file.cdf');

% Create a variable in the file.
varNum = cdflib.createVar(cdfid,'Grades','cdf_int1',1,[],true,[]);

% Write data to the variable
cdflib.hyperPutVarData(cdfid,varNum,0,[],int8(98))


%Clean up
cdflib.delete(cdfid);
clear cdfid
