Hi Jeyhun,

If you know the values of x and y, then you can use the plot function. This line of code creates a plot of the data in y versus the corresponding values in x.

plot(x,y)

For more information, see plot.

For example if your y = a*cos(x), you can use plot like this:

x = 0:1e-2:20; %x values
a = 2; %can be anything constant number
y = a*cos(x);
plot(x,y)
