Scilab Function
Last update : 16/12/2004

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)`

### Parameters

- `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);
