Preallocating a variable that changes size every for loop iterations.

I am using a variable indices that changes size like three times in an iteration .Preallocating it does not change anything.

When I run the code it says the variable needs prealloaction.I am bulding masks here that will help me like constraints in a GA code.

It's just a code suggestion, you can safely ignore it.

[Sindar]

you do have a typo: "companiey_limit=size..."

Thank you for you answer. But still I ignore that and it gives me error in the last line of if loop:company_index_map(company)=[i] .it says :Error using containers.Map/subsasgn

Specified key type does not match the type expected for this container.

Error in pro_2_mkp_1 (line 47)

company_index_map(company)=[i];

That's an entirely separate issue. If you want help on that, create a new question with the relevant code as a code block (not an image)
