# plot2d1

2D plot (logarithmic axes). **This function is obsolete.**

### Calling Sequence

plot2d1(str,x,y,[style,strf,leg,rect,nax])

### Arguments

- str
is a string of length three

`"abc"`

.- a
can have the following values:

`e`

,`o`

or`g`

.- e
means "empty". Itspecifies the fact that the value of

`x`

is not used (the`x`

values are supposed to be regularly spaced, ie 1:<number of rows of`y`

>). The user must anyway give a value for`x`

, 1 for instance:`plot2d1("enn",1,y)`

.- o
means "one". If there are many curves, they all have the same x-values:

`x`

is a column vector of size nl and`y`

is a matrix of size (nl,nc). For example :`x=[0:0.1:2*%pi]';plot2d1("onn",x,[sin(x) cos(x)])`

.- g
means "general".

`x`

and`y`

must have the same size (nl,nc). Each column of`y`

is plotted with respect to the corresponding column of`x`

.`nc`

curves are plotted using`nl`

points.

- b, c
can have the values

`n`

(normal) or`l`

(logarithmic).- b=l
a logarithmic axis is used on the x-axis

- c=l
a logarithmic axis is used on the y-axis

- x,y,[style,strf,leg,rect,nax]
these arguments have the same meaning as in the

`plot2d`

function.- opt_args
these arguments have the same meaning as in the

`plot2d`

function.

### Description

This function is obsolete. USE `plot2d`

INSTEAD !!

`plot2d1`

plots a set of 2D curves. It is the same as
`plot2d`

but with one more argument `str`

which
enables logarithmic axis. Moreover, it allows to specify only one column
vector for `x`

when it is the same for all the curves.

By default, successive plots are superposed. To clear the previous
plot, use `clf`

.

Enter the command `plot2d1()`
