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().
