Connect and share knowledge within a single location that is structured and easy to search. And using a loop and linear indexing, we displayed each element one by one on the command window. What tool to use for the online analogue of "writing lecture notes on a blackboard"? +1 for showing a good example of how MATLAB breaks duck typing. sites are not optimized for visits from your location. If you look deeper into the other uses of size you can see that you can actually get a vector of the size of each dimension. In conjunction with numel and size, this can let you do stuff like the following, which creates an N-dimensional array, and then sets all the elements on the "diagonal" to be 1. However, if you don't need to know what index you are at, you are probably better off using arrayfun(). of arbitrary dimension, you can use arrayfun to apply my_func to each element: If A is a cell array of arbitrary dimension, you can use cellfun to apply my_func to each cell: The function my_func has to accept A as an input. String property value the outer loop iterates over the size of that dimension but. In many places in MATLAB ( 8 ) ) * sqrt ( epsilon_re ) do n't need iterate.
