Function pinverse 

pub fn pinverse<T>(
    input: &Array<T>,
    tolerance: f64,
    option: MatProp,
) -> Array<T>
where
    T: HasAfEnum + FloatingPoint,

Psuedo Inverse of Matrix

Parameters

• input is input matrix
• tolerance defines the lower threshold for singular values from SVD
• option must be MatProp::NONE (more options might be supported in the future)

Notes:

• Tolerance is not the actual lower threshold, but it is passed in as a parameter to the calculation of the actual threshold relative to the shape and contents of input.
• First, try setting tolerance to 1e-6 for single precision and 1e-12 for double.

Return

Pseudo Inverse matrix for the input matrix
