xarrows(2)

NAME
xarrows - draw a set of arrows

CALLING SEQUENCE
[]=xarrows(nx,ny,[arsize])

PARAMETERS

nx  : real matrix of size (n1,n2)

ny  : real matrix of size (n1,n2)

arsize
    : real scalar (size of the arrow head).

DESCRIPTION
This function draws a set of arrows which are given by the vector or matrices nx and ny. The ith arrow is defined by (nx(i),ny(i))-->(nx(i+1),ny(i+1)). nx, ny can also be matrices :
nx=[ xi_1,x1_2,...; xf_1,xf_2,...]
ny=[ yi_1,y1_2,...; yf_1,yf_2,...]
in which case the arrows are (xi_k,yi_k)->(xf_k,yf_k)

This function uses the current graphic scale which can be set by calling a high level drawing function such as plot2d.

SEE ALSO
plot2d, xchange.
