Thank you Jan,
Y is the vehicle speed, X is the time min interval, and N is the indication if there is an accident or not (if there is it will be written as Yes in the row)

@Lina Alhelo: For Matlab X, Y and N are arrays of a certain type. It does not matter, if they represent vehicles, US$ or intergalactic spaceships. But it does matter, if they are ouble vectors, cell strings, string arrays, etc. and what values they have. Therefore a short explicit example of input data is more useful than explaining the physical meaning of the variables.

places = find(strcmp(N, 'Yes'));
now plot() using 'MarkerIndices', places

Hi Lina,
I understood that, based on the 'N' condition, you want to communicate whether accident took place or not. I have tried from my end and below is the solution for the same. I made the below code from my understanding towards this question.
In the code depending upon the 'N' value initially, the "if" condition displays a graph or a message. In this test case, I have tried to display the "cos" graph when the condition is satisfied. In your project kindly set up the required graph. Also note that, saying "Yes" is same as "True" and logical value "1" [Yes==True==1].
N = 1
if N == 1
Accident()
else
display("No accident, everyone are safe")
end
function Accident()
f=5;
time=2;
Ts=1/100;
t=Ts:Ts:time;
x=(cos(2*pi*f*t));
plot(t,x)
end
For detailed information and for other case implimentations on "if" condition, refer to this link
Hope I have addressed your question and you find it helpful!
