fplot2d 2D plot of a curve defined by a function (obsolete)

## Syntax

                fplot2d(xr,f,[style,strf,leg,rect,nax])
                fplot2d(xr,f,<opt_args>)

## Arguments

xr

  vector.

f

  external of type `y=f(x)` i.e. a scilab function or a dynamically linked routine referred to as a string.

style,strf,leg,rect,nax

  see `plot2d`

<opt_args>

  see `plot2d`

## Description

fplot2d() is obsolete and will be removed from Scilab 6.2.x. Please use plot(xr,f,..) instead.

`fplot2d` plots a curve defined by the external function `f`. The curve is approximated by a piecewise linear interpolation using the points `(xr(i),f(xr(i))`. The values of f(x) are obtained by `feval(xr,f)`.

Enter the command `fplot2d()` to see a demo.

## Examples

    deff("y = f(x)", "y = sin(x)+cos(x)")
    x = [0:0.1:10]*%pi/10;
    fplot2d(x,f)

deff("[y]=f(x)","y=sin(x)+cos(x)") x=[0:0.1:10]*%pi/10; fplot2d(x,f)

    clf
    fplot2d(1:10,'parab')

deff("[y]=f(x)","y=sin(x)+cos(x)") x=[0:0.1:10]*%pi/10; fplot2d(1:10,'parab')

## History

6.1.1 fplot2d() is declared obsolete, to be removed from 6.2.x. plot(x,f) replaces it.
