# hist3d

3D representation of a histogram (**obsolete**)

### Syntax

hist3d(mtx,[theta,alpha,leg,flag,ebox]) hist3d(mtx,<opt_args>) hist3d(list(mtx,x,y),[theta,alpha,leg,flag,ebox]) hist3d(list(mtx,x,y),<opt_args>)

### Arguments

- mtx
matrix of size

`(m,n)`

defining the histogram`mtx(i,j)=F(x(i),y(j))`

, where`x`

and`y`

are taken as`0:m`

and`0:n`

.- list(mtx,x,y)
where

`mtx`

is a matrix of size`(m,n)`

defining the histogram`mtx(i,j)=F(x(i),y(j))`

, with`x`

and`y`

vectors of size`(1,m+1)`

and`(1,n+1)`

.- <opt_args>
This represents a sequence of statements

`key1=value1`

,`key2=value2`

,... where`key1`

,`key2,...`

can be one of the following:`theta`

,`alpha`

,`leg`

,`flag`

,`ebox`

. See plot3d.- theta,alpha,leg,flag,ebox
see plot3d.

### Description

Up to Scilab 6.0, `hist3d()` features are actually some
`bar3d()` ones. In Scilab 6.1.0, `bar3d()` is
introduced as a clone of `hist3d()` . From now on, please use
`bar3d()` in replacement of the former `hist3d()` .
`hist3d()` will be redefined in Scilab 6.2.0 to actually support 3D
histogram features. |

`hist3d`

represents a 2d histogram as a 3D plot.
The values are associated to the intervals ```
[x(i) x(i+1)[ X [y(i)
y(i+1)[
```

.

Enter the command `hist3d()`

to see a demo.

### Examples

hist3d();

hist3d(10*rand(10,10));

### History

Version | Description |

6.1.0 | The current implementation of hist3d() is declared obsolete. Use bar3d() instead. |
