matrix, returning a row vector of 1's and 0's. The second one,

l, becomes

TRUE if all elements of a vector are nonzero. For vectors,

l returns 1 if

none of the elements of the vector are zero. Otherwise it returns 0. For

matrices,

l operates on the columns of the matrix, returning a row vector

of 1's and 0's. View the following code to understand these tow functions.

Matlab’s command:

>> clear all; z=[-5 2 0]; x=[5 0 -1; 2 4 8]; y=[2 1 -1; 1 2 4];

>> a1=any(z), a2=any(x), a3=any(y), a4=all(z), a5=all(x), a6=all(y)

Matlab’s response:

a1 =

a2 =

1 1 1

a3 =

1 1 1

a4 =

a5 =

1 0 1

a6 =

1 1 1

4.2. Conditional Statements

The above section has been introduced since it is necessary for the

evaluation of conditional statements as well as loop expressions (see the

following section). A conditional statement is a segment of programming

code that evaluates a statement; if the statement is TRUE then it executes

some commands, otherwise if it is FALSE it runs a bulk of different

programming code. The two most important conditional statements that

Matlab materialize, is the

f statement and the

h statement.
