Hi
I'm very new to matlab, and I'm having trouble plotting a graph of an equation
The equation is
y = e - (a*T^2)/(T + b)
Where the values of e, a, and b are constants.
The only varialbe I have is T. I want to plot y for a range of T values from 0 to 600. But whenever I input this equation in matlab, it calculates y to be a single value, 1.1019 and this is depressing me. How can I get the plot i'm trying to find?
Thanks

Hello, you could create an anonymous function and pass the values of "T" through this anonymous function. Watchout for the elementwise operations below:
myfunc=@(x) e-(a.*x.^2)./(x+b);
y=myfunc(T); % this will output an array with each value in "y" corresponding to a value in "T"
