Vector field

Vector fields in the plane can be used to analyze first degree differential equations: open parentheses table row cell x with dot on top left parenthesis t right parenthesis end cell row cell y with dot on top left parenthesis t right parenthesis end cell end table close parentheses equals space F left parenthesis x comma y right parenthesis

vector_field(List)

Given a list with the function F (a two-elements list), returns a vector field object ready to be plotted.

vector_field(List, Identifier)

Given a list with the function F (a two-elements list) and an identifier (the first variable of the system: x following the notation above), returns a vector field object ready to be plotted.

Below is a complete list of options that may be used in the vector_field function.


Option Description Format Default value
vertical_divisions Number of vertical divisions to be plotted Natural. {vertical_divisions=25} By default, the best number is selected.
horizontal_divisions Number of horizontal divisions to be plotted Natural. {horizontal_divisions=25} By default, the best number is selected.
