How to call a function properly.
显示 更早的评论
I want to take a function file and call it into my script. I have this function:
function ff = fCW()
F = @(f,Re) 2*log10(Re*sqrt(f))-0.8-(1/sqrt(f));
Re = linspace(1e4,1e7,6);
ff = zeros(size(Re));
for k = 1:length(Re)
ff(k) = fzero( @(f) F(f,Re(k)), 0.05 );
end
end
And I want to call it into this script file:
clear all, close all
Re1=linspace(1e+4,1e+7,6); NRe1=length(Re1);
fB = zeros(size(Re1)); fSJ = fB;
for i=1:NRe1
fSJ(i)=0.25/(log10(5.74/Re1(i)^0.9))^2;
fB(i)=0.3164/Re1(i)^0.25;
end
I want to plot(Re, fCW, Re1, fSJ, Re1, fB).
Is there an easy way to do this?

Did you run it as you posted? Did it work?
If all the relevant vector pairs have the same lengths: (Re,fCW), (Re1,fSJ), (Re1,fB), the plot call should work as you wrote it.
