Attempted to access x(2); index out of bounds because numel(x)=1.

Hello, I have the problem of dimensions when executing the function of Genetic algorithms

how can I solve this problem :

'Attempted to access x(2); index out of bounds because numel(x)=1'

here is the code :

function L=ga1(x)

load FM.mat;

load L0.mat;

load Lmsd.mat;

load Lrst.mat;

FM=FM(:,1);

L0=L0(:,1);

Lrst=Lrst(:,1);

Lmsd=Lmsd(:,1);

FT=x(1)*L0+x(2)*Lrst+x(3)*Lmsd;

L=abs(FM-FT);

end

'Attempted to access x(2); index out of bounds because numel(x)=1'

function L=ga1(x)
  ..
  FT=x(1)*L0+x(2)*Lrst+x(3)*Lmsd;
  ...

You passed only a single value for x when you called your function gal. Must have at least three elements by your expression above.
