Hi,

Please help me in this little part of code:

....script.................................................

clear all

Xa=input('----------cood. x do ponto A: ')

AB=input('----------AB diametro maior da ELIPSE: ')

Za=Xa;

A=[Xa 0 Za]

xx=[Xa Za AB]

function y(x)=XbZb(xx)

y(1)= (x(1)-xx(2))/(x(2)-xx(1))*xx(1)+0-x(2);

y(2)=(x(1)-xx(1))^2+(x(2)-xx(2))^2-xx(3)^2;

endfunction

[x,info]=fsolve("XbZb",[1;1])

B=[x(1) 0 x(2)]

.....end script........................................

Octave Terminal answer:

>>>parse error near line 11 of file G:\erro.m

syntax error

>>> function y(x)=XbZb(xx)

                            ^

==========================

Then I  change to:

function y=XbZb(xx)

Octave Terminal answer:

>>>error: `x' undefined near line 12 column 8

error: called from:

error: XbZb at line 12, column 5

error: C:\Programas\3.2.4_gcc-4.4.0\share\octave\3.2.4\m\optimization\fsolve.

m at line 177, column 6

error: G:\erro.m at line 16, column 9

thanks
