this is my cod; cpoint=unidrnd(69-1);

but this code gives error. How can I do it

Thanks advance.

Do you want a random integer value or just any old number between 1 and 69?

The next time you draw a random number, are you going to want to exclude the previously drawn number (like if you're simulating a lottery drawing, where once a numbered ball is drawn it cannot be drawn again)?

Take a look at the randi (random integers with replacement), randperm (random integers without replacement), or rand (random numbers) functions.

I want to pick random integers between 1 and 69. I can re-select the number I chose.

I am working on genetic algorithm.

I will cross between two individuals. I need the cutting point to be able to crisscross. I want to randomly select an integer between 69-1 for the cut-off point. I want the number I selected to change every time I run the code.
