Interval coordinate-wise estimates for a set of attainable states of a linear stationary system. III

A class of linear stationary systems is studied for which interval coordinate-wise estimates can be found in a simple way for a set of achievable states where the matrices which determine the system are specified in interval form. These estimates are found through solution of a set of linear algebraical equations with interval coefficients which are found thrpugh solution of a set of linear algebraical equations with interval coefficients which are found directly from matrices of the initial system. Conditions are found under which a solution of this set of interval equations is found by conventional (rather than interval) methods.
