to make a graph(2D), it's super easy. help me!

Hi. I'm trying to make 2D graph for the equation of volatility in the range of 0<=x<=1. so I wrote the cords like this.

>> x=[0:1];
>> y=x.*a/{1+x.*(a-1)}

and I also tried these.

x=[0;0.1;0.2;0.3;0.4;0.5;0.6;0.7;0.8;0.9;1];
x=[0:0.1:1];

However, every time I try it, I get the message that 'mrdivide is a defined function in case of 'cell' input arguments.(this might not be certain as I translate it from my native language to English.)

I think it's about matrix problem. Help me!

Curly braces ‘{}’ denote cell arrays in MATLAB. I don’t see any reason for you to use a cell here.

Does this do what you want?

x=[0:0.1:1]; 
a = 5;
y=x.*a./(1+x.*(a-1));

figure(1)
plot(x,y)
grid

Thanks for the quick answer. but I have one more question. why the dot with a(a.) is necessary in third line?

That's so you divide element-by-element instead of doing a matrix divide (inverse).

Thank you, Image Analyst!
