Hello all, I have to compare two datasets (a= 89072 x 13 & b=89268 x 37) that must have the same rows, so I have to remove the rows that are not common. The columns number for the two dataset are not the same, so I can't 'Intersect' them. How can I remove these rows please?
Thank you

But there are 13 columns in one and 37 in the other so you are going to have to define some type of definition for "same". Once you've defined "sameness", then we can help identify and remove.

What do you mean by " I have to remove the rows that are not common"? if you mean to reduce the size of the other dataset(b) and make it equal to
a,
then you can use
b(1:length(a),:)
