示例1: GetSubmatrix
/**
Gets a 3x3 matrix consisting of all cells besides those along the given row or column.
*/
Mat3x3 GetSubmatrix(const Mat4x4& m, int row, int col)
{
int nextRow = 0;
int nextColumn = 0;
Mat3x3 result = Mat3x3::Zero();
//we will loop through each element of our 4x4;
//if the current element is valid (neither on the same row as [row] or column as [col])
//then set Mat3x3(nextRow, nextColumn) and increment nextColumn
//then increment nextRow
//the last step might not be necessary
for (int i = 0; i < MAT4X4_NUM_CELLS; i++)
{
//if this row is valid...
if (i != row)
{
//reset nextColumn
nextColumn = 0;
for (int j = 0; j < MAT4X4_NUM_CELLS; j++)
{
if (j != col)
{
result(nextRow, nextColumn) = m.AtCoordinate(i, j);
nextColumn++;
}
}
//move nextRow down a row
nextRow++;
}
}
return result;
