.so ../sci.an
.SH NAME
fplot2d - 2D plot of a curve defined by a function
.SH CALLING SEQUENCE
.nf
fplot2d(xr,f,[style,strf,leg,rect,nax])
fplot2d(xr,f,<opt_args>)
.fi
.SH PARAMETERS
.TP 15
xr
: vector.
.TP
f
: external of type \fVy=f(x)\fR i.e. a scilab function or a
dynamically linked routine referred to as a string.
.TP
style,strf,leg,rect,nax
: see \fVplot2d\fR
.TP
<opt_args>
: see \fVplot2d\fR
.LP
.SH DESCRIPTION
\fVfplot2d\fR plots a curve defined by the external function \fVf\fR.
The curve is approximated by a piecewise linear interpolation using the points
\fV(xr(i),f(xr(i))\fR. The values of f(x) are obtained by \fVfeval(xr,f)\fR.
Enter the command \fVfplot2d()\fR to see a demo.
.SH EXAMPLE
.nf
deff("[y]=f(x)","y=sin(x)+cos(x)")
x=[0:0.1:10]*%pi/10;
fplot2d(x,f)
xbasc();
fplot2d(1:10,'parab')
