fplot2d

2D plot of a curve defined by a function

Calling Sequence

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 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.

Sample Examples

deff("[y]=f(x)","y=sin(x)+cos(x)")
x=[0:0.1:10]*%pi/10;
fplot2d(x,f) clf();
deff("[y]=f(x)","y=sin(x)+cos(x)")
x=[0:0.1:10]*%pi/10;
fplot2d(x,f)
fplot2d(1:10,'parab')
