Evstr(resu(k)) is a paste error - I'm reading an asci file :) Without using a loop, I would like to get the n th component of the vector resu(k) ... k is no more no less than the index of specific lines I'm trying to get ...
Through your answers I'm understanding that I'm thinking on a bad way Paul EXPORT CONTROL : Cet email ne contient pas de données techniques This email does not contain technical data De : users [mailto:[email protected]] De la part de antoine monmayrant Envoyé : vendredi 1 juin 2018 11:55 À : [email protected] Objet : [EXTERNAL] Re: [Scilab-users] submatrix issue Hello, What do you wan to achieve exactly? As Stéphane pointed out, the sizes are not the same. When you assign something like: A=B; You have two different situations: 1) size(A)==size(B) 2) size(B)=[1,1] In the first case, you assign each element of B to each element of A. In the latter case (which corresponds to your commented line), B is just a scalar that gets assigned to each element of A. In the current situation, you are neither in case 1) nor in case 2). As you have size(NodesMatrix2(i,j+1))=[300,300] and size(resu(k))=[300,1], you might want to replicate resu(k) 300 times and fill NodesMatrix2(i,j+1) with these 300 copies. If this what you want to do, here is the code: NodesMatrix2(i,j+1)=resu(k)*ones(1,300); By the way, why do you use "evstr(resu(k))" instead of "resu(k)"? Antoine Le 01/06/2018 à 11:45, Stéphane Mottelet a écrit : It cannot work since --> size(k) ans = 300. 1. --> length(i)*length(j) ans = 90000. i.e. NodesMatrix2(i,j+1) has 90000 elements and resu(k) has 300 S.
