MATLAB: Matrix Dimensions Must Agree

dimension

if true
% code
end
clear
clc
lg=0.0005;
ls=0.0005;
i=2.3;
N=1300;
g=0.002;
g1=linspace(0.002,0.0001,0.0225);
h=0.5;
r=0.2;
nuo=4*pi*10e-7;
B=nuo*N*i/(g1+r*g/(2*h));
Hi i have this code and i got the error 'Matrix dimensions must agree.' I am making a noobly mistake for sure but i am a beginner. How can i fix that? After doing the calculations i need to plot(B,g1). Thank you for your help.

Two problems:
1. Your ‘g1’ vector is empty. The length (optional third argument) to linspace must be an integer greater than 0. Any other values return an empty array.
2. You need to vectorise the first division (change / to ./) in your ‘B’ assignment:
B = nuo*N*i./(g1+r*g/(2*h));
