示例1: mult
DoubleMatrix mult(DoubleMatrix& m2, ComplexMatrix& m1)
{
// Check dimensions
unsigned int m1_nRows = m1.numRows();
unsigned int m2_nRows = m2.numRows();
unsigned int m1_nColumns = m1.numCols();
unsigned int m2_nColumns = m2.numCols();
if (m1.size() == 0)
{
return real(m1);
}
if (m2.size() == 0)
{
return m2;
}
DoubleMatrix result(m1_nRows, m2_nColumns);
if (m1_nColumns == m2_nRows)
{
for (unsigned int row = 0; row < result.numRows(); row++)
{
for (unsigned int col = 0; col < m2_nColumns; col++)
{
double sum = 0.0;
for (unsigned int k = 0; k < m1_nColumns; k++)
