# 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 fplot2d() is obsolete and will be removed from Scilab 6.2.x. Please use plot(xr,f,..)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)```
```clf
fplot2d(1:10,'parab')```

• paramfplot2d — animation dans le plan d'une courbe définie par une fonction

### History

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