Re: error while plotting

[bharat pathak]

Hello Srinivas,

 

       You are trying to create cell arrays though that is not your intention.

 

        Try this.

 

        a = [1 2 3];

        b = [1 4 9];

        plot(a, b);

 

Regards

Bharat Pathak

Subject: error while plotting

Dear Sir/Madam,

I recently downloaded the latest version of Octave from internet. The installation was successful, and when I tried to execute a simple code to plot the variables a and b, I received the following error message.

octave-3.0.1.exe:1> a={1,2,3};
octave-3.0.1.exe:2> b={1,4,9};

I've installed octave for windows version and am running Windows XP Professional edition (64 bit) on my computer. Can you please help me to fix this issue?
