function and indexing erros

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.

Walter Roberson can you more explecite please to how to use them on memory, i'm runing the code on the script m.file shouldn't he call the variables and data that is on the path file! ?

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
