Find and remove a value from an array
显示 更早的评论
Hello! I'm trying to find in an array 'done' the position of a value 'next' without the use of a loop. Then, in this array i want to remove from that position found, the existing element.
out=find(done==next);
done(out)=[];
I tried it this way but is doesnt seem to work. Would you find an arror or recommend another way?

Hi Zenia Askar,
Assuming the content of your variables 'done' and 'next' are numeric your code cannot remove a single value from the matrix without destroying the matrix structure. You should apply logical indexing rather than using 'find()'.
done(done == next) = [];
The result does not represent the matrix structure anymore but is a vector then. To omit that you can place a NaN-value instead.
done(done == next) = NaN;
Kind regards,
Robert
