[Saad Rana]

actually I have to convolve these two signals but I couldn't draw either of these signals

[Sriram Tadavarty]

Saad, i suggest you to go through MATLAB onramp course here https://www.mathworks.com/learn/tutorials/matlab-onramp.html

To solve this particular problem, you could go through the links of plot, conv functions. Once try with the links and they will help.

Try this:

x = linspace(-1, 3);
y = 2*((x >= 0) & (x < 1)) + 1*((x >= 1) & (x < 2));

figure
stairs(x, y)
grid
axis([-1  3    -1  3])

If you're trying to create a plot that has a particular appearance but you're not sure which function can create such a plot, open the Plots tab on the Toolstrip. This includes a gallery where you can look at small thumbnails and see which function was used to create each. Find a plot that looks similar to what you want and look for help or doc on the function whose name appears below the thumbnail.

If you select the data you want to plot in the Workspace window, you can even filter that list to those functions that are appropriate for the selected data.
