paramfplot2d

animated 2D plot, curve defined by a function

Calling Sequence

paramfplot2d(f,x,theta)
paramfplot2d(f,x,theta,flag)
paramfplot2d(f,x,theta,flagrect)

Arguments

x

real vector.

f

function y=f(x,t) . f is a Scilab function or a dynamically linked routine (referred to as a string).

theta

real vector (set of parameters).

flag

string 'no' or 'yes': If "yes" screen is cleared between two consecutive plots.

rect

"rectangle" [xmin, xmax, ymin, ymax] (1 x 4 real vector),

Description

Animated plot of the function x-->f(x,t) for t=theta(1),theta(2),etc. f can be a either Scilab function or a dynamically linked routine since y=f(x,t) is evaluated as y=feval(x(:),t,f). See feval. f: mapping x,t -> f(x,t) = R^N valued function for x= vector of R^N and t=real number. x is a N-vector of x-values and for each t in theta, f(x,t)=N-vector of y-values.

Examples

deff('y=f(x,t)','y=t*sin(x)')
x=linspace(0,2*%pi,50);theta=0:0.05:1;
paramfplot2d(f,x,theta);
