What does this command mean?

What does the following command in the plot parenthesis mean?

ylinscale = ylin*DelF;

plot(tlin,ylin(:,2))

plot(tlin, 150+ylinscale(:,1))

Of course this a system with differential equations, a nonlinear one, and it works fine. But my question is what does it mean to write plot(tlin,ylin(:,2)) and 150ylinscaale? I couldn't find it in help in Matlab. Can you explain it to me please?

Thanks!

It might be overloaded, but it's likely just the plot command. I'm surprised you couldn't find it, since "help plot" would have turned it up.

Hello Mr Cyclist. I know that is not very polite but... I wonder if you could help me:

[Walter Roberson]

ylin(:,2) means to extract column 2 of the variable named ylin

plot(tlin, ylin(:,2)) means to draw a plot using tlin as the x axis values, and using column #2 of ylin as the y axis values.

plot(tlin, 150+ylinscale(:,1)) means to draw a plot using tlin as the x axis values, and using 150 more than column #1 of the array ylinscale as the y axis values.
