Warning: Error updating FunctionLine
显示 更早的评论
I have written 3 simple lines of code to plot a function. Here is my code:
n=2;
omega=@(r) log(factorial(r+n-1))-log(factorial(r))-log(factorial(n-1));
fplot(omega,[0 150],'b')
When I plot it, it gives me the following error message: "Warning: Error updating FunctionLine".
In case this information is useful, the function is the natural log of the multiplicity of an Einstein Solid. The multiplicity is given by 
. Where n is the number of oscillators and r is quanta of energy. When we take natural log, we get 
. I checked in the command window, and the largest factorial that MATLAB can calculate is the factorial of 170, but it never has to calculate the factorial of a number greater than 170 while 
.

factorial is only for integers but fplot uses nonintegers

You could recode in terms of gamma
