Function dqcsim::bindings::dqcs_mat_approx_eq

#[no_mangle]pub extern "C" fn dqcs_mat_approx_eq(
    a: dqcs_handle_t, 
    b: dqcs_handle_t, 
    epsilon: c_double, 
    ignore_gphase: bool
) -> dqcs_bool_return_t

Approximately compares two matrices. >

a and b are borrowed matrix handles. epsilon specifies the maximum element-wise root-mean-square error between the matrices that results in a positive match. ignore_gphase specifies whether the check should ignore global phase.

If ignore_gphase is set, this checks that the following holds for some x:

\f[ A \cdot e^{ix} \approx B \f]

This function returns DQCS_TRUE if the matrices match according to the aforementioned criteria, or DQCS_FALSE if not. DQCS_BOOL_ERROR is used when either handle is invalid or not a matrix. If the matrices differ in dimensionality, DQCS_FALSE is used.
