I was able to do this using with an if-else statement (as shown below), but am unsure of how to convert it to a switch case. I know that I could put every single permutation of each case name in an array, but I wanted to know if there was an easier way to do that.

function state = stateAbbreviation(inputStr)
origState = upper(inputStr);
alabamaStr = 'Alabama';
alabamaAbrev = 'AL';
alaskaStr = 'Alaska';
alaskaAbrev = 'AK';
arizonaStr = 'Arizona';
arizonaAbrev = 'AZ';
kansasStr = 'Kansas';
kansasAbrev = 'KS';
caliStr = 'California';
caliAbrev = 'CA';
if strcmpi(origState, alabamaStr)
    state = "AL";
elseif strcmpi(origState, alabamaAbrev)
    state = "Alabama";
elseif strcmpi(origState, alaskaStr)
    state = "AK";
elseif strcmpi(origState, alaskaAbrev)
    state = "Alaska";
elseif strcmpi(origState, arizonaStr)
    state = "AZ";
elseif strcmpi(origState, arizonaAbrev)
    state = "Arizona";
elseif strcmpi(origState, kansasStr)
    state = "KS";
elseif strcmpi(origState, kansasAbrev)
    state = "Kansas";
elseif strcmpi(origState, caliStr)
    state = "CA";
elseif strcmpi(origState, caliAbrev)
    state = "California";
else 
    disp('Unknown')
end
end

For a switch statement try this:

function state = stateAbbreviation(inputStr)
switch upper(inputStr)
    case 'ALASKA'
        state = 'AK';
    case 'AK'
        state = 'Alaska';
    case 'ALABAMA'
        state = 'AL';
    case 'AL'
        state = 'Alabama';
    otherwise
        disp('Unknown State')
end
end
