indexing - Matlab. I got some errors - 


l_0=1.5;  l_1=1.6;   lambda_min=2*(1+1)*l_0;  lambda_max=2*(1+1)*l_1;  n_0=linspace(2,2.11,10); n_1=linspace(2.30,2.50,10); i=1:10    j=1:10    k=1:10     l(i) = lambda_min * ( lambda_max/lambda_min)^(i/10)      sum=sum(l)     d_0(:,j)= l(i)/((n_0(i)/n_1(i)+1))                     d_1(:,k)= (n_0(i)/n_1(i))*d_0(:,j)        end    end  end

first of all; want find values of l(i) vector, take sum of vector. second, d_0(:,j) want create matrix can plot later, takes different values l(i),n_0,n_1 each time. if take values n_0 , n_1 , put in loop index error because should logic or integer number.

my matrix overwritten , not know how avoid it. note, want in d_0 , d_1 n_0 , n_1 take values linspace. example in first iteration n_0= 2 n_1= 2.30 second iteration take next value in linspace.

i tried see value of n_0(i) , give me 10 iterations. gives me more that overwritten.

try:

l_0=1.5;  l_1=1.6;   lambda_min = 4*l_0;  lambda_max = 4*l_1;   n_0 = linspace(2,2.11,10) % don't add semicolon can check giving 10 values n_1 = linspace(2.30,2.50,10) %  i=1:10       l(i) = lambda_min * ( lambda_max/lambda_min)^(i/10) % should give 10 values  end   d_0= l./((n_0./n_1+1)); % give vector, not matrix.                 d_1= (n_0./n_1).*d_0;     lsum = sum(l); % should give 1 value

i have been trying send post request website, , has not been loading full site. i guessing problem node js not loading javascript content, executing it. can see javascript in response, though never loads content javascript files producing in html. what mean is, doesn't execute javascript. how make node js code overcome this, , wait the full website load? have tried native code, , "request' module, both producing same errors. if helps, don't need native javascript. modules fine. some code have tried (request module): var options = { method: 'post', uri: 'https://url', formdata: { 'email': 'email', 'prize': '0', 'transactional': 'on' }, headers: { /* 'content-type': 'application/x-www-form-urlencoded' */ // set automatically } }; rp(options) .then(function (body) { console.log(body) }) .catch(function (err) { console.log(err) }); when fetch content...
