~ Ex.:

function myInterp(x,v,method)
    arguments
        x (1,:) {mustBeNumeric,mustBeReal}
        v (1,:) {mustBeNumeric,mustBeReal,mustBeEqualSize(x)}
        method (1,:) char {mustBeMember(method,{'linear','cubic','spline'})} = 'linear'
    end
    % Function code
    ....
end
 
% Custom validation function
function mustBeEqualSize(a,b)
    % Test for equal size
    if ~isequal(size(a),size(b))
        eid = 'Size:notEqual';
        msg = 'Size of first input must equal size of second input.';
        throwAsCaller(MException(eid,msg))
    end
end

MATLAB has a pretty way of declareing what an argument can and can’t be, {mustBeText} {mustBeNumeric} ecc.

If you want to create a new mustBeSomething function above is the way to do it.
