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 This function is obsolete.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This function is obsolete.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() to see a demo.

Examples

// multiple plot without giving x
x=[0:0.1:2*%pi]';
plot2d1("enn",1,[sin(x) sin(2*x) sin(3*x)])
// multiple plot using only one x
clf()
x=[0:0.1:2*%pi]';
plot2d1("onn",x,[sin(x) sin(2*x) sin(3*x)])
// logarithmic plot
x=[0.1:0.1:3]';
clf();
plot2d1("oll",x,[exp(x) exp(x.^2) exp(x.^3)])
