{
DoubleMatrix result = GetMatrix( inExp );
if( result.empty() || result[ 0 ].empty() )
{
bcierr << "Could not get scalar value \"" << inExp << "\"" << endl;
result.resize( 1, vector<double>( 1 ) );
}
return result[ 0 ][ 0 ];
}示例2: mxCreateNumericMatrix
bool
MatlabEngine::PutMatrix( const string& inExp, const DoubleMatrix& inValue )
{
int sizeDim2 = inValue.empty() ? 0 : inValue[ 0 ].size();
mxArray* val = mxCreateNumericMatrix( inValue.size(), sizeDim2, mxDOUBLE_CLASS, mxREAL );
double* data = mxGetPr( val );
if( data )
{
int indices[] = { 0, 0 };
