[Scilab-users] Loop query - Scilab 5.5.2

Or you can build a three column array as a matrix.  Here's my example,
but I don't see where 'x' is defined.

Te = (5000:10000:25000)';
D = E * Te .^ 3 / (12 * (1 - v^2));
lambda = ((rho_m - rho_fill) * g ./ (4 * D)) .^ 0.25;
lambda_k = lambda * 1000;
flex = (2 * Pb * lamda / ((rho_m-rho_fill)*g)) .* ..
       exp(-lamda_k .* x) .* cos(lamda_k .* x);
