The continue statement in MATLAB is used to pass control to the next iteration in for and while statements. Let’s suppose someone wants to find and print the value of k^2-50 for all integers in [-10,10] domain. The mfile for that is given below.

% For integers k=-10,-9,….,9,10,

% the function k^2-50 will take positive as

% well as negative values.

%For example, for k=-9, k^2-50=31; for k=1,

% k^2-50=-49; for k=8, k^2-50=14.

% The loop below will calculate values of k^2-50 for

% all values of requested k.

for k=-10:1:10

val=k^2-50;

fprintf(‘\n k=%g val=%g’,k,val)

end

Let’s suppose now you are asked to calculate and print value of k^2-50 for all integers in [-10,10] domain but only if (k^2-50) is positive.

% The loop below will calculate and print values of k^2-50

% for all values of the requested k

% for which k^2-50 is positive.

for k=-10:1:10

if (k^2-50<0)

continue;

end

val=k^2-50;

fprintf(‘\n k=%g val=%g’,k,val)

end

Can you do what you did above using the while statement. Yes, the MATLAB code is given below.

% Equivalent in while

% The loop below will calculate values of k^2-50

% for all values of the requested k for which k^2-50 is positive.

k=-10;

while (k<=10)

if (k^2-50>0)

val=k^2-50;

fprintf(‘\n k=%g val=%g’,k,val)

end

k=k+1;

end

Interesting site 🙂 I just started using matlab and this site is helping me get used to it.

I didn’t realise it could do so much.

Great. Can you share more about what you were trying to do and the code to go along with it?
