function y = isfinite(x) %ISFINITE True for finite elements of symbolic arrays. % ISFINITE(X) returns an array that contains 1's where % the elements of X are finite and 0's where they are not. % For example, isfinite(sym([pi NaN Inf -Inf])) is [1 0 0 0]. % % For any X, exactly one of ISFINITE(X), ISINF(X), or ISNAN(X) % is 1 for each element. % % See also SYM/ISINF, SYM/ISNAN. x = privResolveArgs(x); y = logical(feval(symengine, 'symobj::map', x{1}, 'stdlib::isfinite')); end
