MATLAB Programming Data Types and Operators

    Add, Subtract, multiply, divide, backer operators:

     %addition

     a = 1 + 2

     %subtraction

     b = 2 - 1

     %multiplication

     c = a

     %division

     d = a / b

     %exponentiation

     e = a ^ b

    The modulo action allotment the butt if the arguments are disconnected together, so a modulo b agency the butt if a is disconnected by b.

     %modulo

     butt = mod(a,b)

    The boolean operators are accustomed by the characters & (boolean AND) | (boolean OR) and ~ (boolean NOT /negation). A amount of aught agency false, any non-zero amount (usually 1) is advised true.

    Example:

     >>%boolean AND

     >> y = 1 & 0

     y = 0

     >> y = 1 & 1

     y = 1

     >>%boolean OR

     >> y = 1 | 0

     y = 1

     >> y = 1 | 1

     y = 1

     >>%boolean antithesis (NOT)

     >>y = ~1

     y = 0

    Equality b

     ans = 1

     >>a=5;b=3;

     >>a=b

     a = 3

    Note that in the first case, a amount of 1 (true) is returned, about for the additional case a gets assigned the amount of b.

    Greater than, beneath than and greater than or according to, beneath than or according to are accustomed by >, <, >=, <= respectively. All of them acknowledgment a amount of true or false.

    Example:

     >>a=3;b=5;

     >>a<=b

     ans = 1

     >>b
     ans = 0

    The antithesis operation in MATLAB is accustomed by the attribute ~, which turns any False ethics into True and carnality versa:

     >> c = (a == b)

     c = 1

     >> ~c

     ans = 0

    This is all-important because conditionals (IF/SWITCH/TRY) and loops (FOR/WHILE) consistently attending for statements that are TRUE, so if you wish it to do something alone if the account is False you charge to use the antithesis to change it into a true statement.
