I want to plot a vector field and I want it to only show the vectors at certain points. I can write the function in such a way that the points I want to see occur at integer values of two parameters. But I am unable to tell VectorPlot how to increment my parameters.
I notice that when making a Table, I'm able to write
to increment $i$ by $di$ from $imin$ to $imax$, but if I try to add a fourth term like this when specifying ranges for my parameters in VectorPlot, it does not work. How can I accomplish the same effect in VectorPlot?
