__Function file:__ **ellipse(m,n,a,b,q,fmt) **

This function plots an ellipse defined by:

- 1 ellipse - centre of is in [m,n] a length of half-axis "a" and "b"; all values are scalars
- n-ellipses - centres of is in [m,n] a length of half-axis "a" and "b"; all values are vectors (expect fmt)

Parameters

*m,n* describe centre of the ellipse in axes x,y.

Parameters

*a,b* describe length of main and lateral half-axis.

Parameter

*q* is for change compute points on the ellipse, so quality.

Parameter

*fmt* describe format of ellipse lines. You can change format of lines (color and style) and format of points.

Example:

*
ellipse([5,3],[-2,0],[5,2],[3,5],[80,50]);*

__Function file:__ **hyperbola(m,n,a,b,v,q,fmt)**

This function plots a hyperbola, defined by:

- 1 hyperbola - centre of is in [m,n] and length of half-axis "a" aand "b"; all values are scalars
- n-hyperbolas - centres of is in [m,n] and length of half-axis "a" and "b"; all values are vectors (expect fmt)

Parameters

*m,n* describe centre of the hyperbola in axes x,y.

Parameters

*a,b* describe length of main and lateral half-axis of teh hyperbola.

Parameter

*v* is high of the hyperbola.
Parameter

*q* is for change compute points on the hyperbola, so quality.

Parameter

*fmt* describe format of hyperbola lines. You can change format of lines (color and style) and format of points.

Example:

*
hyperbola(2,2,2,5,10,60,"k--");*

__Function file:__ **parabola(m,n,p,v,q,type,fmt)**

This function plots a parabola, defined by:

- 1 parabola - centre of is in [m,n] and length of half-axis "a" and "b"; all values are scalars
- n-parabolas - centres of is in [m,n] aand length of half-axis "a" and "b"; all values are vectors (expect fmt)

Parameters

*m,n* describe centre of the parabola in axes x,y.

Parameters

*a,b* describe length of main and lateral half-axis of the parabola.

Parameter

*v* is high of the parabola.
Parameter

*q* is for change compute points on the parabola, so quality.

Parameter

*fmt* describe format of parabola lines. You can change format of lines (color and style) and format of points.

Example:

*
parabola([0 1],[0 -2],[2 -2],[10 10],[50 70],"xy");*
