What is the error here?

clear all clc; alfa=0.5; bet=2; lan=1; teta=2; mu=0.5; n=4; k=2; s=0; syms u for j=k:n s=s+(factorial(j-1)/(factorial(k-1)*factorial(j-k)))*((-1)^(j-k))... (factorial(n)/(factorial(j)*factorial(n-j)))(exp(-alfa*j*((u/(1-u))^bet))); end;

integral(s, 0, 1,'ArrayValued',true )

Please format your code.

There are some syntax errors.

clear all 
clc; 
alfa=0.5; 
bet=2; 
lan=1; 
teta=2; 
mu=0.5; 
n=4; 
k=2; 
s=0; 
syms u 
for j=k:n 
    s=s+(factorial(j-1)/(factorial(k-1)*factorial(j-k)))*((-1)^(j-k))... % missing operator (+ or * maybe?) here, between ")" on this line and "(" on the next line
        (factorial(n)/(factorial(j)*factorial(n-j)))(exp(-alfa*j*((u/(1-u))^bet))); 
%                                                  ^^ missing operator (* maybe?) here
end; % extra 'end'
end
integral(s, 0, 1,'ArrayValued',true )

Making a guess at putting in those 2 missing operators, there is still an error in the usage of integral():

clear all 
clc; 
alfa=0.5; 
bet=2; 
lan=1; 
teta=2; 
mu=0.5; 
n=4; 
k=2; 
s=0; 
syms u 
for j=k:n 
    s=s+(factorial(j-1)/(factorial(k-1)*factorial(j-k)))*((-1)^(j-k))*... 
        (factorial(n)/(factorial(j)*factorial(n-j)))*(exp(-alfa*j*((u/(1-u))^bet))); 
% end;
end
integral(s, 0, 1,'ArrayValued',true )

Error using integral
First input argument must be a function handle.
