if statement to skip certain values in loop

I have a range of X and Y values, and I have a domain that I don't want to calculate the values of nodes within. I want to have an if statement within a loop in Matlab to skip these.

X

Y

if

For example:

X = [1:20]

Y = [1:20]

X = [5:7]

Y = [12:14]

I think the code should be something like this:

for X=1:20
for Y=1:20
if X=2:7 & Y=12:14
return
end
% the operation here !
T(X,Y) = lab lab lab
end
end


However, I'm not sure how to properly write the condition.

You could use ismember or a combination of any and == for the condition, and continue is the command for skipping to the next loop index...

ismember

any

==

continue

% ismember example
for X = 1:20
for Y = 1:20
if ismember( X, 2:7 ) && ismember( Y, 12:14 )
continue
end
% your loop operations
end
end


In this case, you could replace the if condition with

if

if any( X == 2:7 ) && any( Y == 12:14 )
