How to assign NaN to consecutive elements of a vector, in intervals defined by a matrix

Hello there!

supose we have a vector x=1:12

and we have a controling matrix as this:

z=[2 4; 6 8; 10 11]

We want to assign NaN in x in the intervals in z for 2 to 4, 6 to 8 and 10 to 11, in order to get:

x_new= [ 1 NaN NaN NaN 5 NaN NaN NaN 9 NaN NaN 12]

Many thanks in advance for your time

did you mistakenly type the wrong intervals for x ?

Dear Mohammad, you are right. I have edited the original question and corrected the values.

Thank you

Try this:

N = numel(x);
idx = any((1:N >= z(:,1) & 1:N <= z(:,2)));
x(idx) = NaN;
