problem plotting with octave

hello everybody

I have to plot a graphic with in the y's my vector called x of 100 elements, and in the x's my other vector of 10 elements. the computer tells me that they have this vectors mus be he same length but I don't think so. this is he code

    function gaussiana()

    x=rand(1,100)

    vet=[0,0,0,0,0,0,0,0,0,0]

    for k=1:1:100,

     if x(1,k)<0.1,

     vet(1)=vet(1)+1;

     else if x(1,k)<0.2,

     vet(2)=vet(2)+1;

     else if x(1,k)<0.3,

     vet(3)=vet(3)+1;

     else if x(1,k)<0.4,

     vet(4)=vet(4)+1;

     else if x(1,k)<0.5,

     vet(5)=vet(5)+1;

     else if x(1,k)<0.6,

     vet(6)=vet(6)+1;

     else if x(1,k)<0.7,

     vet(7)=vet(7)+1;

     else if x(1,k)<0.8,

     vet(8)=vet(8)+1;

     else if x(1,k)<0.9,

     vet(9)=vet(9)+1;

     else if x(1,k)<1,

     vet(10)=vet(10)+1;

     end;

     end;

     end;

     end;

     end;

     end;

     end;

     end;

     end;

     end;

     end;

     vet

     plot(x,vet)

     end function gaussiana()

and this is the error it gives me

can some one help me?

thanks

Your title and your tags have been corrected to reflect that your problem is in Octave code, not in MATLAB code.

Answer 1

[Walter Roberson]

You are trying to plot a vector of length 100, x, against a vector of length 10, vet.

By the way, have you considered using histc() ?

Or considered using MATLAB instead of Octave?
