Doubt in Matlab

Many MATLAB functions and operators default to double (double-precision floating point), but some functions and operators work with other object types too. For example, if you type 2+2, the answer 4 will be double. If you type x=int8(2) and then x+x, the answer 4 will be int8.

If you wish to identify the type of an object, try the 'class' function. For example, class(pi) returns the string 'double'.

Re: Doubt in Matlab

from Matlab help:
"ISLOGICAL(X) returns true if X is a logical array and false otherwise.
Logical arrays must be used to perform logical 0-1 indexing."
eg.
>> x=[0 1 0 1 0 0 1]

x =

0 1 0 1 0 0 1

>> y=logical(x)

y =

0 1 0 1 0 0 1

>> z=islogical

z =

1
in workspace, y and z are both logical class,...
For the second question "Yes", float is the default...

it means that the array will contain only binary 1s and 0s.

So the array which contains that kind of elements is known as logical array. Is that right?

What is logical class

Open your MATLAB help navigator, and search for "logical types".
It explains that data type, and gives various examples.
