fec(2) Scilab Function fec(2)
NAME
fec - contour level of a function defined on a triangular mesh
CALLING SEQUENCE
fec(x,y,triangles,func,no,Ntr,strflag,legend,brect,aaint)
PARAMETERS
x,y : two vectors of size no, (x(i),y(i)) gives the coordinates of
node i
func : a vector of size no : func(i) gives the value of the function
for which we want the level curves.
triangles : is a [Ntr,5] matrix. Each line of triangles specifies a trian-
gle of the mesh triangle(j) = [number,node1,node2,node3,flag].
node1,node2,node3 are the number of the nodes which constitutes
the triangle. number is the number of the triangle and flag is an
integer not used in the fec function
rest : for the remaining arguments strflag,legend,brect,aint, see
plot2d
DESCRIPTION
See the demo files demos/fec.
fec.ex1 is a simple demo file in which a mesh and a function on that mesh
is completely built in Scilab syntax
fec.ex2 is an example for which the mesh and the function value where com-
puted by an external mesh builder (amdba type mesh) and an external pro-
gram. A set of macros ( provided in file macros.sci) can be used to read
the data files in Scilab and plot the results.
