Creating a logical array

hi guys,

How can i create a logical array [1 0 1 0 1 1 ....] 1-by-15 it will go into gamultiobj with bitstring so the the arranging is not important.

 x=boolean([0 1 0 1 0 1 0  1])

Note: the boolean function is only in the Stateflow toolbox which is kind of rare. See the warning in the help:

The operator boolean is supported only in Stateflow® charts. In MATLAB®, use logical.

If you don't have the Stateflow toolbox, use logical as shown in the other answers below. Actually, even if you do have it, I think you should use logical instead, especially for portability of your code.

To get a random placement of trues and falses, use randi

logicalArray = logical(randi(2, [1 15]) - 1)

logicalArray = 1×15 logical array
   1   1   1   1   0   0   0   1   1   0   1   0   0   0   1

Otherwise you can put in exactly what you want:

logicalArray = logical([1, 0, 1, 0, 1, 1])

logicalArray = 1×6 logical array
   1   0   1   0   1   1

What's the ultimate goal? If you need to initialize a logical array, you can use true or false:

either

logicalArray = false(1,15);

-OR-

logicalArray = true(1,15);

will initialize a 1x15 logical array that you can then set the individual values for, then if you set any element, like

logicalArray(5) = 1;

It will be of type logical rather than double.

If you already know your entire array, you can also do it manually with true and false:

logicalArray = [ true false true false true true true false true false true true true false true ];

will output

1 x 15 logical array
[ 1 0 1 0 1 1 1 0 1 0 1 1 1 0 1]
