Trouble using strings in If statements using OR

I am trying to loop through and use IF statement as example:

if race == "H2" | "H1" | "H3" | "H4"

but I get error "Error using |

Input must be text or pattern."

If I try: race == "H2" || "H1" || "H3" || "H4"

I get error:

Conversion to logical from string is not possible.

"H1" and so forth are strings in Matlab

Thank you!

[_]

if race == "H2" || race == "H1" || race == "H3" || race == "H4"

[Walter Roberson]

Or alternately

if ismember(race, ["H1", "H2", "H3", "H4"])
