jQuery Match Height's files and documentation can be found here.

Create a file called match.js to house the matchHeight function:

jQuery(document).ready(function($) {

    $(function() {
        $('.match').matchHeight({
            byRow: true,
            property: 'height',
            target: null,
            remove: false
        });
    });
    
});

This code goes in your theme's functions.php to enqueue the matchHeight script as well as the script that initializes it.

function match_height_scripts() {
    if ( is_post_type_archive( 'issue' ) ) {
        wp_enqueue_script( 'match-script', get_stylesheet_directory_uri() . '/js/jquery.matchHeight-min.js', array( 'jquery' ) );
        
        wp_enqueue_script( 'match-custom-script', get_stylesheet_directory_uri() . '/js/match.js', array(), '1.0', true );
    }
}
add_action( 'wp_enqueue_scripts', 'match_height_scripts' );
