# spZeros¶

## Purpose¶

Creates a sparse matrix containing no non-zero values.

## Format¶

y = spZeros(r, c)
Parameters
• r (scalar) – rows of output matrix.

• c (scalar) – columns of output matrix.

Returns

y (RxC sparse matrix) – sparse matrix containing no non-zero values.

## Examples¶

sparse matrix y;

// Create a 4x3 sparse matrix with all elements set to 0
y = spZeros(4, 3);

// Create a dense matrix with the same values as 'y'
d = spToDense(y);


The contents of d are equal to:

0 0 0
0 0 0
0 0 0
0 0 0


## Remarks¶

Since sparse matrices are strongly typed in GAUSS, y must be defined as a sparse matrix before the call to spZeros().
