is an option to NDSolve and related functions that specifies the initial step size to use in trying to generate results.

Examples

Basic Examples  (1)Summary of the most common use cases

Specify the step size for NDSolve to use for starting the integration of an ODE:

In[1]:=1

Out[1]=1
In[2]:=2
✖
https://wolfram.com/xid/0cpq1nledkzadm-cyb30b
Out[2]=2

Without this specification, features at the beginning of the interval may be missed:
