I want to ask for a function f (X) with the command "INPUT" ... then create the function F1 = f(i*X).
example: f(X)=1/(1+0.2*X+5*X^2) => F1(X)=1/(1+0.2*i*X+5*(i*X)^2)
EXPORT test()
BEGIN
LOCAL f;
IF INPUT(f,"ENTER f with single quote. Example: '1/X' ") THEN
F1:=subst(f,X,'(i*X)');
END;
END;
I try :
F1:=expr("subst(f,'X','(i*X)')");
with another local var g :
g:=subst(f,X,'(i*X)');
F1:=g;
or :
CAS("F1:=subst(f,X,'(i*X)')");
I try also with string and the command REPLACE See my previous post...
I do not see it very clear... Thanks for your help.
