using the output of
ode45, ode23, ode113, ode15s, ode23s,
ode23t, ode23tb, or bvp4c.
erfcinv
Inverse complementary error function.
tetramesh
Tetrahedron mesh plot for use with delaunayn.
triplot
2-D triangular plot for use with delaunay.
Math Functions with New or Changed Capabilities
Function Enhancement/Change
bvpinit
New syntax solinit = bvpinit(sol,[anew bnew])
extrapolates a solution
sol as an initial guess for solving a
BVP on an extended interval. It can copy parameters from
the previous iteration or let the user to provide new ones.
For more information, see “Boundary Value Problems for
ODEs” in the MATLAB documentation.
bvpset
New Vectorized option lets you pass to the solver bvp4c
an array of column vectors. This allows
bvp4c to reduce
the number of function evaluations, and may significantly
reduce solution time. For more information see “Boundary
Value Problems for ODEs” in the MATLAB
documentation.
convhull
New syntax [K,a] = convhull(x,y) returns the area a of
the convex hull.
convhulln
New syntax [K,v] = convhulln(X) returns the volume v
of the convex hull.
