[Scilab-users] Loop query - Scilab 5.5.2

[Lester Anderson]

Thanks for the solution(s). Had to change the flex line to get it
working in 5.5.2:

flex = 2*Pb*lamda/((rho_m-rho_fill)*g)*exp(-lamda_k*x).*cos(lamda_k*x);

Otherwise it gave an error of undefined variable (flex). The three
column array did not work; looking it to that one.

checked

x=linspace(0,200,41); is a row vector

//test
dist=linspace(0,200,41);
x(:,1)=dist'
// convert to column vector)
