plot a mathmatical function

function is called that will plot a mathematical function in one variable and in range 0 to 10 and function should recive input vector of integer and it has n length even. for example func([100,1500,3000]) will plot that number of points

[Walter Roberson]

it has n length even

I do not understand that part?

[Roger Nadal]

length should be even

[Walter Roberson]

In your example, should it produce three plots, one with 100 points, one with 1500, one with 3000? If so then should they all be on the same plot or should subplots be used?

[Roger Nadal]

Three different plots and has to give input mathematical expression for example sin(x)+x

Answer 1

[Nicolas Douillet]

Perhaps you should have a look at linspace.

u = linspace(1500,3000,16); % since there are 16 values between 1500 and 3000 with a sampling step of 100

figure;

plot(u);

I am not sure this is what you want to do, since your question is not so clear to me.

Hope this could help you anyway.

Best,

Answer 2

[Walter Roberson]

funstr = input('Enter expression in variable x ', 's');
fun = str2func(vectorize(funstr));

x = linspace(0,1,NumberOfPoints);
y = fun(x);
plot(x, y);

Now generalize this slightly to support multiple plots.

[Roger Nadal]

It shows error on linspace and Numberof points

[Walter Roberson]

Have you considered the possibility of naming the function parameter NumberOfPoints ?

[Roger Nadal]

I didn’t understand?
