How to Draw Vector Fields in Julia
Code
quiver(, quiver=)
In Julia, the quiver()
function can be used to visualize a vector field.
θ = 0:0.2:2π
quiver(cos.(θ),sin.(θ), quiver = (-sin.(θ), cos.(θ)), size = (600,600), lims = (-2,2)); png("1")
Changing the Length of Arrows
There might be a better way to change the size of the arrows, but essentially, you can draw a better picture by increasing or decreasing the length of vectors provided by the quiver=
option.
quiver(cos.(θ),sin.(θ), quiver = (-sin.(θ), cos.(θ)) ./ 2, size = (600,600), lims = (-2,2)); png("2")
