PURPOSE ^

CHECKDATAINTEGRITY Check state estimation input data integrity.

SYNOPSIS ^

function [success, measure, idx, sigma] = checkDataIntegrity(measure, idx, sigma, nbus)

DESCRIPTION ^

CHECKDATAINTEGRITY  Check state estimation input data integrity.
   returns 1 if the data is complete, 0 otherwise.
   NOTE: for each type of measurements, the measurement vector and index
   vector should have the same length. If not, the longer vector will be
   truncated to have the same length as the shorter vector.
