fplot2d

2D plot of a curve defined by a function

Syntax

fplot2d(xr, f)
fplot2d(xr, f, style)
fplot2d(xr, f, style, strf)
fplot2d(xr, f, style, strf, leg)
fplot2d(xr, f, style, strf, leg, rect)
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.

Examples

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