GA file exchange code need help

Hi there,

https://www.mathworks.com/matlabcentral/fileexchange/67435-the-genetic-algorithm-ga-selection-crossover-mutation-elitism

I am trying to modify the GA code (link above) by changing the population type using the following:

%generate population of 0s and 1s

%M=no. of chromosomes

%N=no. of genes in chromosomes

population = randi([0 1], M , N);

%for every 1 in population randomly assigns number between 1 to 15

population(population==1)=randi([1 15], 1, nnz(population));

it doesn't work as i get error "dot indexing not supported for this variable type"

can someone please help.

It is not clear where you are putting that code. If you are putting it inside initialization() then the problem is that initialization() must return a struct looking like

population.Chromosomes(i).Gene(j) = value

but you are returning a pure numeric array.

Yes i am trying to put it inside initilization. is it possible to convert numeric array to structure?

or how to include the type of data i am generating in this file exchange code?

I basically want to change the data and objective function.

You can use num2cell with the dimension parameter to split by rows or columns giving a cell array. You can pass that cell array to struct() as the value, causing it to create one structure member for each cell entry.
