Purpose¶

Writes a variable to a GAUSS Data Archive.

Format¶

retcode = gdaWrite(filename, x, varname)¶

Parameters

filename (string) – name of data file.
x (matrix or array or string or string array) – data to write to the GDA.
varname (string) – variable name.

3	File write error.
4	File read error.
5	Invalid data file type.
9	Variable name too long.
11	Variable name must be unique.

Examples¶

// Generate random variable x
x = rndn(100, 50);

// Create GDA `myFile`
retcode1 = gdaCreate("myfile.gda", 1);

// Write `x`  to `myfile` as x1
retcode2 = gdaWrite("myfile.gda", x, "x1");

Remarks¶

gdaWrite() adds the data in x to the end of the variable data in filename, and gives the variable the name contained in varname.
