Operands to the and && operators must be convertible to logical scalar values.
Error in uiscopes.ScopeCLI/checkSource (line 92) if ~isnumeric(fps) isnan(fps) isinf(fps) ~isreal(fps)
Error in matlabshared.scopes.UnifiedScope (line 105) checkSource( hScopeCfg.ScopeCLI );
Error in uiscopes/new (line 22) hScope = matlabshared.scopes.UnifiedScope(hScopeCfg, varargin{:});
Error in implay (line 60) obj = uiscopes.new(hScopeCfg);
Error in JDT (line 7) implay(Out, [-182 292]);

The second argument to implay() is the framerate in FPS. It's a scalar. I have no idea why you're passing it a vector including negative values, but that won't work.
