- Hello,
My question is: What's the difference between using logical masks in a function file and then calling it in a script file vs. writing an anonymous function for it in the script vs. not using an anonymous function in a script? When would you use each case? Also, can you use an anonymous function in a function file?

When a logical mask is scanning a matrix of numbers, is it possible to ask the mask to check for two conditions? For example, something like:
variable = (condition && condition) .*value +...
(condition) .....
