示例1: scalar
void Transpose::scalar(const var& iVar, var& oVar) const
{
// Note that we need to transpose the view too. If it's allocated, it's
// transposed at allocation; if it's supplied it's assumed to be correct
// already. This leaves the in-place case; this happens after the
// operation.
// Transpose always broadcasts to array()
broadcast(iVar, oVar);
// Transpose view if necessary
if (iVar.is(oVar))
{
// Swap the trailing dimensions
int d = iVar.dim();
Heap* h = iVar.heap();
int& str1 = h->stride(d-1);
int& shp1 = h->shape(d-1);
int& str2 = h->stride(d-2);
int& shp2 = h->shape(d-2);
int tmp = shp1;
shp1 = shp2;
shp2 = tmp;
str2 = shp1 * str1;
}
}示例2: vector
void Transpose::vector(var iVar, ind iOffsetI, var& oVar, ind iOffsetO) const
{
assert(oVar);
int dim = iVar.dim();
ind rows = iVar.shape(dim-2);
ind cols = iVar.shape(dim-1);
if (iVar.is(oVar))
// In place transpose
switch (iVar.atype())
{
case TYPE_FLOAT:
inPlace<float>(oVar.ptr<float>(iOffsetO), rows, cols);
break;
case TYPE_DOUBLE:
inPlace<double>(oVar.ptr<double>(iOffsetO), rows, cols);
break;
default:
throw error("Transpose::vector(): unknown type");
}
else
// Transpose to new location
switch (iVar.atype())
{
case TYPE_FLOAT:
outOfPlace<float>(iVar.ptr<float>(iOffsetI), rows, cols,
oVar.ptr<float>(iOffsetO));
break;
case TYPE_DOUBLE:
outOfPlace<double>(iVar.ptr<double>(iOffsetI), rows, cols,
oVar.ptr<double>(iOffsetO));
break;
default:
throw error("Transpose::vector(): unknown type");
}
