These keypresses run asynchronous with MATLAB and therefore MATLAB does not wait on these keypresses to occur before continuing on with the rest of the script. I am currently using a pause(delay) method but I would like to eliminate the use of a pause and just have Java communicate to MATLAB that it has completed the sequence of robot operations. I am thinking if Java can return a variable/value to MATLAB, I can have MATLAB wait on this variable to arrive before executing the rest of the script. Please let me know if this is possible. Thank you.
