In m-files, we employ Matlab built-in functions or toolbox functions to compute something. Pause(5) can do it but the problem is that it pauses all other callback functions to execute (including other timer functions I am using in the MATLAB GUI, for example). will create a figure if none already exists. It is very annoying to have miscellaneous printouts from un-related functions, when trying to compute a final value. The relentless improvement in speed of computers continues. The original question "Can anyone tell me if there is a way (in MATLAB) to check whether a certain value is equal to any of the values stored within another array?" can be solved without any loop. Matlab supports namespaces for the functions that you write, but the core of Matlab is without namespaces; every function is defined in the global namespace. The parameter types, as well as the return type of a function cannot be incomplete class types, except for deleted functions (since C++11). Why wouldn't you want to use the inbuilt function? Otherwise - write your own. I currently have written two any functions with different inputs depending on the array size. If the determinant of the matrix is zero, then the inverse does not exist and the matrix is singular.
