Check numbers in a 5x5 array
显示 更早的评论
I want to write a script that checks if a 5x5 array contains all the numbers from 1 to 25 but im failing to do so. Do you have any ideas?

Sufficients Hints:
#Check all the elements within 1 & 25, use logical statement to avoid loops
result=data>=.... & data<=....;
#Multiple all elements, if 1 yes, if 0 no
result=prod(result,'all')

If this is indeed the goal (which I doubt), using the all function instead of prod would probably have a better perfomance.

You can also do this without any loops using MATLAB's intersect function which lists the common elements between two arrays. Hint: if you have two 5x5 arrays and one of them contains the values 1:25 then how many elements will they have in common if the other array also contains the values 1:25
