How can I write the code of this line ?

Hello

    E_PI=sqrt((xm-x_I)^2+(ym-y_I)^2);
    E_PZ=sqrt((xm-xr)^2+(ym-yr)^2);
    E_BZ= sqrt((x1(index1)-xr)^2+(y1(index1)-yr)^2);
    r_1=E_BZ+E_PI;
    r_2=E_BZ-E_PZ;

Assume that I have r1 and r2 and n=100, How can I write the following line which runs.Thanks in advance:)

For the above purpose, how is rand(k,1) defined?

[Walter Roberson]

The code looks like it is intended to generate n random values in the range r1 to r2. If so then

R = (r1 - r1) * rand(n, 1) + r1;

Maybe?

    % code
n = 100;
for j = 1:n
     R(j) = r2 - r1)*(randi([1 j],1,1) + r1);
end

Thanks for your reply (randi([1 j],1,1) or (randi([1 j],1)?

I do not understand why randi is being used here?
