spTrTDense¶
Purpose¶
Multiplies a sparse matrix transposed by a dense matrix.
Format¶
-
y =
spTrTDense(s, d)¶ - Parameters
s (NxM sparse matrix) – sparse data matrix.
d (NxL dense matrix) – dense data matrix.
- Returns
y (MxL dense matrix) – the result of \(s\*d\).
Examples¶
sparse matrix s;
// Create a 4x4 sparse identity matrix
s = spEye(4);
// Create dense matrix
d = rndn(4, 4);
y = spTrTDense(s, d);
Remarks¶
This may also be accomplished by the following code:
y = s'*d;
However, spTrTDense() will be more efficient.
