spToDense

Purpose

Converts a sparse matrix to a dense matrix.

Format

y = spToDense(x)
Parameters:x (MxN sparse matrix) – data
Returns:y (MxN dense matrix) – dense matrix converted from sparse matrix x.

Examples

sparse matrix y;

// Create a 4x4 sparse identity matrix
y = spEye(4);

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

The dense matrix d is equal to:

1  0  0  0
0  1  0  0
0  0  1  0
0  0  0  1

Remarks

A dense matrix is just a normal format matrix.
