+% This function allow calling vis_stream with simply a string of character
+% so it can be used to set parameters after being compiled. Make sure there
+% are no spaces for parameter values or the string will not be parsed
+% properly.

+% Example: vis_stream_comp('samplingrate 200 refreshrate 5 position [100,100,500,500]');
