Dear Sir/Madam,

I am not able to solve the given integration function. The screenshot of given is attached and the code is given below

Thank you

for j=1:100
x(j)=linspace(0,0.025,101);
R(j)=linspace(0,0.4,101);
f=0.025;
syms x
b(j)= int(R(j)-sqrt(R(j).^2-x(j).^2),0, f);
c(j)=sqrt((1/f)*b(j));
end

This cannot work:

x(j) = linspace(0,0.025,101);

On the left is a scalar and on the right a vector with 101 elements.

Seeing only the invalid code does not clarify its intention. What is the purpose of the loop?

I cannot fix the code such that it does, what you want, as long as you do not clarify what you want to achieve. I ask again: What is the purpose of the loop? I'd expect RT to be a constand and x to be a symbolic variable. Then there is no need for a loop.
