Error in SSA (line 87)

Tp=SalpPositions(i,:)>ub';Tm=SalpPositions(i,:)<lb';SalpPositions(i,:)=(SalpPositions(i,:).*(~(Tp+Tm)))+ub'.*Tp+lb'.*Tm;

Answer 1

[Walter Roberson]

Your ub and lb need to be column vectors, not row vectors.

[tahseen alshmary]

How can I write it in column vector ? please

[Walter Roberson]

% Problem preparation 
dim = 14;
ub = 1.1 * ones(dim, 1);
lb = 0.05 * ones(dim, 1);
fobj = @ofun;
%--------------------------------------------------------------------------
SearchAgents_no=20;                 %number of population
Max_iteration=1000;   %number of iteration
%%
[Best_score,Best_pos,SSA_cg_curve]=SSA(SearchAgents_no,Max_iteration,lb,ub,dim,fobj); 

Answer 2

[Alan Weiss]

The error statement is clear: your assignment (equality) statement has a 1-by-14 vector on the left and a 14-by-14 matrix on the right. Take a look at line 87 of your SSA function to see what is wrong. Are those the expected sizes of the variables?

I do not know

my pararmeter is :

% Problem preparation 
dim = 14;
ub = 1.1 * ones(1, dim);
lb = 0.05 * ones(1, dim);
fobj = @ofun;
%--------------------------------------------------------------------------
SearchAgents_no=20;                 %number of population
Max_iteration=1000;   %number of iteration
%%
[Best_score,Best_pos,SSA_cg_curve]=SSA(SearchAgents_no,Max_iteration,lb,ub,dim,fobj);
