MATLAB: How could I use the “find” command to compare two matrices

Question

Hello Matlabers,

I have 2 matrices (with 1 column and 2000 rows each) and I would like to compare each row from each matrix and get a 3rd logical matrix with 1's or 0's depending on the case… so far I tried to use the command:

control_matrix=find(A)<(B);

and this is supposed to generate a control matrix with 1's and 0's with the same size (1 column and 2000 rows) but when I apply the command it does not give me back the correct results…

any idea, suggestion or hint?

thanks! 🙂

Answer 1

Comparing two matrices directly will give back a logical array:

control_matrix= A<B;

The find function will find the index values where items are nonzero.
