2D plot of a curve defined by a function
fplot2d(xr,f,[style,strf,leg,rect,nax])
fplot2d(xr,f,<opt_args>)
: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 :
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).
