I need help with some boolean statements. How do i create a boolean statement with an array. So pretty much i created a 2 3x3 arrays and I need to create a boolean statement to :
A = 3X3 Array
B = 3x3 array
C = 2x3 array
D = 2x3 array
A single boolean (1 or 0), indicating whether or not A contains the number 7
• A single boolean (1 or 0), indicating whether or not D is ALL zeros •
A single boolean (1 or 0), indicating whether or not A and C are equal •
A single boolean (1 or 0), indicating whether or not A and B are equal

What have you done so far? What specific problems are you having with your code? Are you supposed to code this with loops or are you allowed to use MATLAB supplied functions?

You have incorrect syntax. First a big hint: A(:) turns A into a column vector containing all of the elements in a column ordered manner. So you can operate on A(:) to see if any or all of its elements meets a condition. E.g.,
all( A(:) < 4 ) would test to see if all elements of A are less than 4
any( A(:) == 0 ) would test to see if any element of A is equal to 0
Etc.
