feval - multiple evaluation
11
f : function or character string (for Fortran call)
14
Multiple evaluation of a function for one or two arguments of vector
17
z=feval(x,f) returns the vector z defined by
19
z=feval(x,y,f) returns the matrix
23
f is an external (function or routine) depending on one
24
or two arguments which are supposed to be real. The
25
result returned by f can be real or complex. In case of a
26
Fortran call, the function 'f' must be defined in the
27
subroutine ffeval.f (in directory SCIDIR/routines/default)
30
deff('[z]=f(x,y)','z=x^2+y^2');
32
deff('[z]=f(x,y)','z=x+%i*y');
34
feval(1:10,1:5,'parab') //See ffeval.f file
36
// For dynamic link (see example ftest in ffeval.f)
37
// you can use the link command (the parameters depend on the machine):
38
// unix('make ftest.o');link('ftest.o','ftest); feval(1:10,1:5,'ftest')
