Using Matlab

Problem 3 Pre-allocation of memory, zeros, sizeumel/length Pre-allocate memory for the code snippets for (2a) and (2b). Recall that when pre-allocating memory: We do not care about the actual values assigned, although we should still choose a "fast" method. For example, the built-in functions ones or zeros should be used instead of rand Make sure size matches that of the final resultant array . Make sure data type(class) matches as well, e.g. double, logical, char, etc. .Note: if the expected data type is logical, you can still use the built-in function ones or zeros, with an extra input argument "logical', e.g. x zeros (size (mat) , ' logical ' ) ; Alternatively, x will achieve the same thing. false (size (mat) ) ; Example % If do preallocatin of memory, it should be at this line. for i1:length (a) end display (x) % to show values in x 2 1 1x5 logical array 1 1 . Here, the expected size is the size of a or b Here, the expected data type is logical true/false
