I am really new to matlab. When I wrote two functions like this:
funw.m
function q = funw(t)
h=0;
r=1/7;
q = quadl(@(x) sqrt(t^(2*r)-x.^(2*r)),h,t)... -quadl (@(x) sqrt(x.^(2*r)-t^(2*r)),t,(h+2));
return
VentRate.m
function w = VentRate
global elev;
global h;
w = fzero(@funw,(h+elev)/2);
return
I try to use VentRate to call funw, by typing VentRate in the command window, but it will show some error. However, if i directly write w = fzero(@funw,(h+elev)/2) in the command window, it will run without error. So can anyone tell me what is wrong with the second function? I appreciate your help.
Error:
??? Error using ==> fzero at 422 Second argument must be a scalar or vector of length 2.
Error in ==> VentRate at 4 w = fzero(@funw,(h+elev)/2);
