Hello, I am working on a matlab code for school and it is using a while loop. The problem with this is I want the while loop to run until the variable doesn't equal itself.
while R ~= Rc You probably need to change the while loop condition like above. Given the input value for Reynolds number ...

How can I write a 'for' loop that sums up all elements of a vector?
@Seif do you mean like this ? a= [1:5] for i=1:3 c(i)=sum(a(i)+a(i+1)) disp(sum(c)) end
