## Purpose¶

Gets a sparse matrix from a GAUSS Data Archive.

## Format¶

sm = gdaReadSparse(filename, varname)
Parameters
• filename (string) – name of data file.

• varname (string) – name of sparse matrix variable in the GDA.

Returns

sm (sparse matrix) – .- The data contained in the variables in varname.

## Examples¶

// Declare sparse matrix sm1
sparse matrix sm1;

sm1 = gdaReadSparse("myfile.gda", "sm");


## Remarks¶

If gdaReadSparse() fails, it will return a sparse scalar error code. Call scalerr() to get the value of the error code. The error code may be any of the following:

 1 Null file name. 2 File open error. 4 File read error. 5 Invalid file type. 8 Variable not found. 10 File contains no variables. 14 File too large to be read on current platform.
