# Relational Operators

• This is used for comparison of similar parameters whether scalar or non-scalar. With scalars, the operators just output a 1 or 0 signifying true or false for the command statement being considered. When acting on matrices of the same size, the operators carry out an element-by-element comparison thereby creating an output matrix of 1’s and 0’s. The relational operators include:
 Operator Description < Less than <= Less than or equal to > Greater than >= Greater than or equal to == Equal to ~= Not equal to

• Some sample code using relational operators is seen below:

EXERCISE 5

Using the matrices (shown below) carry out the following:

1. Find the product of B and C (name the matrix D). Find the product of C and B (name the matrix E).
2. Find the element-by-element product of the matrices B and C (name it F).
3. Carry out a C greater than B comparison and name the resulting matrix G (do it by hand first)
4. Carry out element-by-element exponentiation of B by G (name H).
5. Compute the columnar product of the elements of H.

MISCELLANEOUS EXERCISE

Complete the sequences observed in matrix C to make a 4-by-6 matrix K (negative integers are allowed).

Convert M into every possible size it could have given the number of elements it possesses.
