Unable to perform assignment because the left and right sides have a different number of elements.

for i=1:100                  
 
  s_code1(i)=strcat(s_code(2*i-1,:),s_code(2*i,:)); 
end
c1=cross(s_code1,100);

s_code = cell(100,1); 
for i=1:100                  
  s_code1{i}=strcat({s_code{2*i-1},s_code{2*i}); 
end

Hi KSSV. Thanku for your response. I tried running the code but it is showing the following error

Unable to perform assignment because brace indexing is not supported for variables of this type.

Ohh..I relaized now.....

S_code is a cell...it is initialized....how you can use again in strcat?? Show us the whole code which you are trying.

Thanku so much for the quick response. I am actually tring to run genetic algorithm.

[KSSV]

What is s_code? In the answer..it is initialized ..so it cannot work...

Hi KSSV. Thanku for the response.Let me try something and will share the code with you.

If you are using R2016b or later, you can also try the following

s_code1 = strings(1, 100)
for i=1:100                  
  s_code1(i)=strcat(s_code(2*i-1,:),s_code(2*i,:)); 
end

Hi @Ameer Hamza. Thanku for your response. I tried running the code but it is showing the following error

Index in position 1 exceeds array bounds (must not exceed 1).

Error in forexam (line 5)

s_code(i)=strcat(s_code(2*i-1,:),s_code(2*i,:));

[Ameer Hamza]

Can you share the value of s_code in a .mat file? Also, can you paste the code you tried running?
