MATLAB Programming Fundamentals - MathWorks

One input is a matrix, and the other is a 3-D array. The dimensions are all either the same or one of them is 1. Compatible Ar ...

Empty Arrays The rules are the same for empty arrays or arrays that have a dimension size of zero. The size of the dimension tha ...

A: 3-by-2 B: 4-by-2 Two nonscalar row vectors with lengths that are not the same. A: 1-by-3 B: 1-by-4 Examples Subtract Vector ...

For example, add a row and column vector. The result is the same as bsxfun(@plus,a,b). a = [1 2 3 4] ans = 1 2 3 4 b = [5; 6; 7] ...

Array Comparison with Relational Operators In this section... “Array Comparison” on page 2-25 “Logic Statements” on page 2-28 Re ...

2 4 6 8 10 12 B = [5 5 5; 9 9 9] B = 5 5 5 9 9 9 A < B ans = 1 1 0 1 0 0 Similarly, you can compare one of the arrays to a sc ...

0 1 1 0 0 1 Empty Arrays The relational operators work with arrays for which any dimension has size zero, as long as both arrays ...

Logic Statements Use relational operators in conjunction with the logical operators A & B (AND), A | B (OR), xor(A,B) (XOR), ...

Operator Precedence You can build expressions that use any combination of arithmetic, relational, and logical operators. Precede ...

The same precedence rule holds true for the && and || operators. Overriding Default Precedence The default precedence ca ...
