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.

When you called it what values did you pass in for WeSolFin, Lc, and Ds?
Also instead of this:
k=6;
for k=1:k
you should just do this
for k=1:6

Image Analyst yes i have the data WeSolFin, Lc and Ds in a file .mat named the same. WeSolFin is a (1,6) Lc and Ds are constants.
for the second point: i was writing it like this befor for k=1:6
and i get errros i'll change that again and i see

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.

EDITED
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
