I have matlab2007 and if i use multiple elseif the program don't run the second or third eleseif. This is the code... x=input('Give x a value x:') if x<-2 f=1 elseif -2<x<3 f=x+1 elseif x>=3 f=x^2 end

The condition in the first elseif statement is not stated correctly. This should work:

xc=inputdlg('Give x a value x:');
x = str2num(xc{:});
if x<-2
f=1
elseif (-2<x) && (x<3)
f=x+1
elseif x>=3
f=x^2
end

@vlad vladut: Note that f is undefined for x==-2.
