Hi i am pretty new to matlab and i was wondering how i can save a "user answer" for a while loop. I mean, so that the question doesn't pop up every time in the loop. The answer to the input should be save throughout the loop.
while det(F) > 0;
N = N-1000; % Initial load decreased
[a, b] = berry(N,E,I,L); % retrieve a and b
[K1,K2]=LS; % 6x6 stiffness matrix fixed-fixed
[beam1,col1]=frame; %<--- (now it is in this function the input is asked)
F = beam + col;
det(F);
end
Depending on the input the user gives, the initial 6x6 matrix is scaled down to a 4x4 matrix.
Hope you can help me! =) hehe

beam_init = false;
while det(F) > 0;
N = N-1000; % Initial load decreased
[a, b] = berry(N,E,I,L); % retrieve a and b
[K1,K2]=LS; % 6x6 stiffness matrix fixed-fixed
if ~beam_init
[beam1,col1]=frame; %<--- (now it is in this function the input is asked)
beam_init = true;
end
F = beam + col;
det(F);
end
