 It is capable of performing, automatically and symbolically, such common procedures as simplification, substitution, differentiation, polynomial factorization, indefinite integration, direct and inverse Laplace transforms, the solution of linear differential equations with constant coefficients, the solution of simultaneous linear equations, and the inverson of matrices.It also supplies fairly elaborate bookkeeping facilities appropriate to its on-line operation.MATHLAB 68 has been used to solve electrical linear circuits using an acausal modeling approach for symbolic circuit analysis.
