WebDec 1, 2012 · Using repmat is by far the most efficient way to preallocate structs : N = 10000; b = repmat (struct ('x',1), N, 1 ); This is ~10x faster using Matlab 2011a than preallocating via indexing, as in N = 10000; b (N).x = 1 The indexing method is only marginally faster than not preallocating. WebA struct array data with 100 elements, each of which has two fields x and y You can initialize an empty struct with data = struct ('x', cell (100,1), 'y', cell (100,1)); and you access each element of the struct array as data (1) and each of these is a struct.
