# Example Matrix comparison functions 007

#### Description

These examples use the comparison functions to do a case-sensitive comparison of two objects of the same type. A Boolean value is returned.

#### Details

Both Matrices are equal.

 (= #(mat| "Hello" "World" ) #(mat| "Hello" "World" )) Returns: true
 (< #(mat| "Hello" "Earth" ) #(mat| "Hello" "World" )) Returns: true
 (> #(mat| "Hello" "Worlds" ) #(mat| "Hello" "World" )) Returns: true

Notes and Hints

If you prefer an integer resulting from the comparison (0 for equal, -1 for less than, and 1 for greater than), use the compare function.
