Although is possible to run these examples via the command window, it is

better to use the Matlab Editor/Debugger to write a script instead. Real

examples with the conditional statements as well as with the loops are

postponed until the introduction of scripts in section 5.

4.2.2 The

h Statement

The

h statement executes groups of statements based on the value of a

variable or expression. The keywords

and

e delineate the

groups. Only the first matching case is executed. There must always be an

d to match the

h. [2]. The expression following the

should be

either a scalar or a string. The syntax of this conditional expression is

tabulated in Table 8.

Syntax Example

switch expression

case

choice #1

segment of executable programming code

case choice #2

segment of executable programming code

otherwise

segment of executable programming code

end

dice=3;

switch (dice)

case 1

disp('One')

case 2

disp('Two')

case 3

disp('Three')

case 4

disp('Five')

case 5

disp('Five')

otherwise

disp('Six')

end

h statement syntax and example.

4.3. Loop Expressions

As mentioned before, loop statements are useful when a segment of

executable programming code is needed to be executed either a specific

number of times, than or as long as an expression is TRUE. The

r and

e loop statements are needed commands when writing efficient

programming code.
