I'd like to solve and store the valves for which bi = 0 across a range i=I
H = 0.1;
I = 200;
bi = zeros(I,1);
for i = linspace(1,I)
bi(i,1) = fzero(@(bi)(bi+H*tan(bi)),0);
end

Ran in:
There is an err in the loop in i = linspace(1,I) leads to non integer value that is NOT acceptable for an index. Here is a corrected code:
H = 0.1;
I = 200;
BI = zeros(I,1); % Memory allocation
b=pi; % Initial solution search near this value: b0
for i = 1:I
b = fzero(@(b)(b+H*tan(b)),b);
BI(i) = b;
end
BI(end) % final solution after 200 iterations
ans = -2.7709e-136
