Hello a newest asking for help.

I have a function to calculate in a loop a variable.

function Ls= WeLatente(WeSolFin,Lc,Ds)
   Ls=zeros(1,6);
   Ls=0; 
   k=6;
   for k=1:k
      Ls(k)=Ls(k)+WeSolFin(k)'*Lc*Ds;
   end

and I get 2 errors messages :

Not enough input arguments.

and

Error in WeLatente (line 6)

Ls(k)=Ls(k)+WeSolFin(k)'*Lc*Ds;

Any help i'll appreciate.

It is not enough that WeSolFin, Lc, and Ds exist in .mat files. You have to load them into memory and you have to pass them in when you call WeLatente

Note that

   k=6;
   for k=1:k
       

is confusing. It would be recommended to use a different variable name for the upper bound than is used for the loop index.

Addendum to sir Image Analyst and sir Walter's comments:

upload your .mat file

https://www.mathworks.com/matlabcentral/answers/118906-passing-a-mat-file-variable-to-a-function#answer_125969

load matlab.mat % load your .mat file  
Ls= WeLatente(WeSolFin{:,:},Lc,Ds) % function call
function Ls= WeLatente(WeSolFin,Lc,Ds)  % function definition
   Ls=zeros(1,6);
   k=6;
   for i=2:k
      Ls(i)=Ls(i-1)+WeSolFin(k)'*Lc*Ds;
   end
end
