#### Explicit

-- Graphic object: explicit (<fcn>,<var>,<minval>,<maxval>) -- Graphic object: explicit (<fcn>,<var1>,<minval1>,<maxval1>,<var2>,<minval2>,<maxval2>) Draws explicit functions in 2D and 3D.

2D

`explicit(<fcn>,<var>,<minval>,<maxval>)` plots explicit function <fcn>, with variable <var> taking values from <minval> to <maxval>.

This object is affected by the following graphic options: `nticks`, `adapt_depth`, `line_width`, `line_type`, `key`, `filled_func`, `fill_color` and `color`.

Example:

```          (%i1) load(draw)\$
(%i2) draw2d(line_width = 3,
color      = blue,
explicit(x^2,x,-3,3) )\$
(%i3) draw2d(fill_color  = brown,
filled_func = true,
explicit(x^2,x,-3,3) )\$```

3D

`explicit(<fcn>,<var1>,<minval1>,<maxval1>,<var2>,<minval2>,<maxval2>)` plots explicit function <fcn>, with variable <var1> taking values from <minval1> to <maxval1> and variable <var2> taking values from <minval2> to <maxval2>.

This object is affected by the following graphic options: `xu_grid`, `yv_grid`, `line_type`, `line_width`, `key`, `enhanced3d`, and `color`.

Example:

```          (%i1) load(draw)\$
(%i2) draw3d(key   = "Gauss",
color = "#a02c00",
explicit(20*exp(-x^2-y^2)-10,x,-3,3,y,-3,3),
yv_grid     = 10,
color = blue,
key   = "Plane",
explicit(x+y,x,-5,5,y,-5,5),
surface_hide = true)\$```

See also `filled_func` for filled functions.

There are also some inexact matches for `explicit`. Try `?? explicit` to see them.

```(%o1)                                true
(%i2) ```
