Respected all
I have successfully got the values for j and v. I have got stuck in solving t due to the problem in finding factorial(c). My question is how to code for factorial term in the expression? Is it possible or I am on the wrong path? As without solving factorial, t cannot be determined. What should I do?
Code attached:
A = linspace(1,10)
C = linspace(1, 11)
[k, c] = ndgrid(A, C)
j=gammainc(c,(0.85));
v=gamma(c.^(-1));
t=0.85.*(1-(((0.85).^5.*(1-(((0.85))./(1-(((0.85)).^6)))))).*1.*(1-((0.85).^5.*(factorial(c)).^-1.*(c.^(5-c).^-1)./(exp(0.85).*k.*v+(0.85).^c.*(1-(0.85./c).^(5-c+1)))/factorial(c).*(1-(0.85./c)))));
The following error is being encountered
Error using factorial
N must be an array of real non-negative integers.
How can this error be removed?
Please help
Regards

N must be an array of real non-negative integers.
To troubleshoot that error message, let's go through the list of possibilities.
% Is c an array or real numbers?
all(isreal(c(:))) % = 1, true
% Is c all non-negative?
all(c(:)>=0) % = 1, true
% Is c all integers?
all(isinteger(c(:))) % = 0! FALSE
There's the problem. C contains non-integers. It makes sense that this would cause an error, right? Factorials are functions of intergers.
factorial(3) = 24
4 * 3 * 2 * 1 = 24
How could that be done with non-integers?

Glad I could help. If you get stuck again with this topic, leave a comment to loop me back in.
