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:

Remarks¶

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