Function: ilt (expr, t, s)

    • The inverse Laplace transform of expr with respect to t and parameter s

    Example:
        (%i) ilt(1/(s+a), s, t);
        (%o) %e^-(a*t)
        (%i) ilt(1/(s+a)^2, s, t);
        (%o) t*%e^-(a*t)

        (%i) ilt((s+a)/((s+a)^2+w^2), s, t);

        (%i) ilt(1/((s+2)^2*(s+3)), s, t);

        (%i) ilt(1/(s*((s+2)^2+1)), s, t);
