Struct LdltResult 

pub struct LdltResult {
    pub pivot_info: DeviceBuffer<i32>,
}

LDL^T factorization result.

Contains pivot information describing the block diagonal structure of D:

• pivot_info[k] > 0: 1x1 pivot block at position k; rows/cols were swapped with row/col pivot_info[k] - 1.
• pivot_info[k] < 0: start of a 2x2 pivot block at positions (k, k+1); rows/cols were swapped with row/col (-pivot_info[k]) - 1.

Fields

pivot_info: DeviceBuffer<i32>

Pivot block sizes: positive for 1x1, negative for start of 2x2.
