; Semicolon

• Signify end of row


• Suppress output of code line

Use semicolons to separate rows in an array creation command, or to suppress the output display of

a line of code.

• vertcat

Separate rows to create an array:

A = [12,13; 14,15]

Suppress code output:

Y = max(A);

Separate multiple commands on a single line (suppressing output):

A = 12.5; B = 42.7, C = 1.25;

B =

42.7000

( ) Parentheses

• Operator precedence


• Function argument enclosure


• Indexing

Use parentheses to specify precedence of operations, enclose function input arguments, and index

into an array.

• “Operator Precedence” on page 2-29


• “Array Indexing”

Precedence of operations:

(A.*(B./C)) - D

Function argument enclosure:

plot(X,Y,'r*')

C = union(A,B)

Indexing:

A(3,:)

A(1,2)

A(1:5,1)
