Drawing using if function

Hi all;

I would like to generate drawing (graph) for Y and X when ever N value is Yes . Can you help me in writting the code

[Jan]

What is the type and contents of X and Y and what is N?

[Lina Alhelo]

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)

[Jan]

@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.

Answer 1

[Walter Roberson]

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!
