I wanted to plot a data in Octave for a logistic regression problem my teacher in my university assigned me to solve. Let's say the input-training features is a matrix X and output is y=1 or y=0 To plot the data I made this statement:
pos = find(y==1);neg = find(y==0); plot(X(pos,1),X(pos,2),’k+’,’LineWidth’,2,’MarkerSize’,7); plot(X(neg,1),X(neg,2),’ko’,’MarkerFaceColor’,y,’MarkerSize’,7);
But it does not compile and it shows the single quotes as unidentified characters. Please help...
