4.3.3. Nested Conditional and Loop Expressions

All conditional and loop statements can be combined in any way that is

desirable. If for example a loop expression includes an

f statement that

nests a

h statement and so on, then, in programming terminology, it is

termed that we have nested statements. As long as the statements are

nested in a logical and a non redundant manner, the user will get correct

answers. View the following example that is exhibited in Table 11 and nests

various statements (figure out their use).

An example of syntax of nested conditional and loop statements

clear; flag=1; x=2*pi; temp=pi;

while x<=4*pi

figure; hold on;

X=temp:pi/10:x;

for j=1:4

subplot(2,2,j); plot(X,sin(j*X)./X, 'b:', 'LineWidth', 3);

switch (j)

case 1

title('Plot of y=sin(x)/x');

case 2

title(' Plot of y=sin(2x)/x');

case 3

title(' Plot of y=sin(3x)/x');

otherwise

title(' Plot of y=sin(4x)/x');

end

xlabel('x'); ylabel('y');

end

temp=x; x=x+pi;

end

4.3.4. Additional Control Flow Statements

Matlab has additional control flow statements that can be used to write an

executable script or function. These are more specialized statements that are

listed in Table 12. You can learn more details via the online help.
