MATLAB: Comparing 2 Matrices Element By Element

compareelementmatricesmatrix

I have 2 matrices A and B, both 7×3. I want to compare each element in A with its corresponding element in B, taking the larger of the 2 values and creating a new Matrix C. Could someone suggest a method on how I would do this? I have seen examples of comparing to find equality between 2 elements but not a comparison to create a new matrix so I am finding this rather difficult.

Thanks in advanced.

Use the max function. Try:

A = rand(3);
B = rand(3);
C = max(A,B)

a = [1 2 3];
b = [1 2 3;
     4 5 6;
     7 8 9];
i = ismember(b , a, 'rows');
c = b(~i,:)

Try this:

a= [1,2,3,4,5] 
b= [-1,-2,-3]
c = a' - b;
c = c(:)'

You get

c =
   2     3     4     5     6     3     4     5     6     7     4     5     6     7     8

in R2016b (I believe) or later that has automatic expansion capability.
