FernandoDuarte`Itovsn3`
ItoReset
​
ItoReset[t,dt]
resets all structures, using
ItoInit
[t,dt]
.

Basic Examples  
(1)
Initialize:
In[1]:=
ItoInit
[t,dt]
Out[1]//TableForm=
Itovsn3 initialized
with time semimartingale t
and time differential dt
Introduce two independent Brownian motions:
In[2]:=
BrownBasis
[{B1,B2},{1,0}]
The two Brownian motions are part of the structure:
In[3]:=
