I want to plot a simple graph with specific x,y coordinates. I can plot when the y values are integers. But i need to plot values like 9/4. this is my error code Attempted to access y(2.25); index must be a positive integer or logical.

i want to plot the points (0,2) (1,9/4) (2,38/17) (3,161/72) (4,682/305)

plot([0 1 2 3 4],[2 9/4 38/17 161/72 682/305])

you can change the YAxes Tick but it seems like you are not familiar with structur arrays nor properties of anything, so it will be hard for you. if you want to have more decimals on your y axes you have to acces the axes-properties .YTick:
>> h=plot(x,y,'.--');
>> h.Parent.YTick=[linspace(2,2.2,3),linspace(2.21,2.25,6)];
