feval
multiple evaluation
Calling Sequence
[z]=feval(x,y,f) [z]=feval(x,f)
Arguments
- x,y
two vectors
- f
function or character string (for Fortran or C call)
Description
Multiple evaluation of a function for one or two arguments of vector type :
- z=feval(x,f)
returns the vector
z
defined byz(i)=f(x(i))
- z=feval(x,y,f)
returns the matrix
z
such asz(i,j)=f(x(i),y(j))
f
is an external (function or routine) accepting
on one or two arguments which are supposed to be real. The result returned
by f
can be real or complex. In case of a Fortran call,
the function 'f'
must be defined in the subroutine
fevaltable.c
(in directory
SCI/modules/differential_equations/src/c
)
Examples
deff('[z]=f(x,y)','z=x^2+y^2'); feval(1:10,1:5,f) deff('[z]=f(x,y)','z=x+%i*y'); feval(1:10,1:5,f) feval(1:10,1:5,'parab') //See ffeval.f file feval(1:10,'parab') // For dynamic link (see example ftest in ffeval.f) // you can use the link command (the parameters depend on the machine): // unix('make ftest.o');link('ftest.o','ftest); feval(1:10,1:5,'ftest')
