Not column, but row wise.
function b = matchPattern(a)
this is actually pretty fun
I'm not proud of this solution, the scoring system is clearly flawed.
Seems like the filter preventing abuse of @eval needs some work!
Nice! I learned something from you.
This solution is wrong. It detects a common patten among any two rows and not just the first row and other rows.
What is the point?
Set some matrix elements to zero
Change the sign of even index entries of the reversed vector
Insert zeros into vector
length of a vector
Triangle of numbers
Return the largest number that is adjacent to a zero
Replace NaNs with the number that appears to its left in the row.
Return the 3n+1 sequence for n
Prime factor digits
