Now ive run into a tricky little problem when attempting to plot the graphs. My interests include engineering mechanics, dynamics, and vibration. The function differentiates each polynomial piece separately, and ignores jump discontinuities between polynomial pieces during differentiation.
Recall that lmi term refers to the elementary additive terms involved in the blockmatrix expression of the lmi. Indefinite integration of a multivariate function, in coordinate directions only, is available via fnderf,dorder with dorder having nonpositive entries.
